Should I buy an nVidia GTX 770 or 760?

yep the 770 is a huge bump over the 760 i was going to recommend a 280x since its 95% of the performance of the 770 for much less but since you want borderlands the 770 its the way to go

As long as you have the money and your CPU will not bottleneck the vga, I dont see why not!

770

770, you get a free borderlands pre sequel

there 770 is worth it if you really want the game as you take the price of the game which is 59.99 and you really only paid an extra 50 for the card and it is a better card

but the big question is what CPU do you plan on using?
as that could be a bottleneck issue and you might be throwing money away

but you should be fine as long as it is at least something around a AMD 6300 even a Intel Dual Core would be fine with that i know some would disagree but the Intel Dual Core beats the 6300 in a lot of gaming test due to AMD lack of single core performance

I would get Ati R9 280x or R9 290x

there are already rumors about the 870, I'd wait a month :o

GTX 770 is much superior(rebrand of GTX 680), than GTX 760(is like rebrand if GTX 660 Ti), GTX 760 is ~ to my Radeon HD 7950. But I would wait for the release of GTX 870 if it's coming soon, but price may be very high, so I would get GTX 770, it's really good, one friend has it.

11 year old PC? Please give us the full specs. Those GPUs might not even run. EDIT: overlooked the part in which you change all the components. :)
If you are 100% positive CPU won't bottleneck them to the ground, I'd say pick the 770.
And the price difference is NOT about the memory/clock speed, but about the extra cores, which is what gives you a rough estimate of the GPU's power, to put it in a simple way.
As other are suggesting, waiting for the 800 series to come out is a good idea, unless you are really wanting to change it now.

Buy a used 670 for half the price and 90% the performance.

gtx 770, but get a decent CPU and MB with it. Also a decent PSU with 600W+ from a good brand.

Get a R9 280 flies away

get the the 770

I got me last year an GTX 650 and im happy.

However im thinking of upgrading next year when the new GTX 880 comes out mostly due to some new games looks like will be needing a little more power.

if i were you check the benchmarks between the two see what they score see the difference are they worth that extra 100$?

I did that with my Card and i felt that I dont want to pay that much extra just for smaller performance difference and my GTX 650 is running everything smooth. sure i cant run Bioshock INfinity on ULTRA but it runs on high quiet fine.

I went with the 770 and have not looked back. Mainly built my PC for BF4 and so glad it can run on max settings 60fps. It will run most modern games nigh on max atm, so would definitely recommend the 770.

The 770 is a complete waste. I have the 760 and it's powerful enough to run every game I've tried on max graphics settings (not counting postprocessing cpu bottleneck)
For $100 get a better CPU and multiple games.
And of course: http://www.logicalincrements.com/

The GTX 880 and 870 are coming out soon (VERY soon,) so don't buy a 7xx now.

Get the r9 290 instead I've seen people sell it for $300 (shipping included) and that card is between 770 and 780

I'm going to hijack the thread. I too have been looking at the 760/770 however my computer guy is suggesting an AMD R9 280X to reduce the risk of bottlenecking. Any thoughts?

AMD is better in gaming..Nvidia is for differend programs like Adobe, Photoshop, Sony etc...
But..your money, your choice..

I was thinking about that aswell, I would prefer the GTX 760 and then buy another video card from the 100$ extra you have in like 2-3 years. Also, you might wanna take a look at the AMD R9 280/280x

My 2 cents:

BL PS will be likely priced around $50 at launch, so if you really want to play it straight away the real difference you're looking at is $50 between the 2 cards. Worth it? It depends: in the first place, if that is really going to be your bottleneck.

However... you haven't even finished playing BL2 yet!

I'd save those $100: unless you're using double monitor or very high resolutions (2560x1440?), the 760 should serve you pretty well for a while and you probably wouldn't even notice the difference with a 770 anyway. By the time you've finished playing the BL2 campaign and have had a bit of fun online, BL PS will have dropped in price, got tweaks and bug fixes that will make it perfectly enjoyable on the 760.

In 2-3 years time use the saved bucks to upgrade the video card if you feel it's become too slow.

PS: I wouldn't dismiss the R9 as crappy, it's a good card, there's a lot of marketing around pushing nvidia but it's not necessarily a better card. Also, keep your PSU in mind and check power consumption of the chosen card.

The smart person would buy the 760 and save the 100 bucks for a future upgrade, the 760 will hook you up for as long as the 770 will, no need to dish out another 100 bucks just like that, when the time comes to upgrade, it will relatively hit the same time period as there isn't that much of a power gap between the two, i'm pretty sure of it.

Of course this will put at risk of some games not being able to run at max quality because the extra kick 770 has would run said game smooth while the 760 struggles to do so.

If i was in your situation i would buy the 760, buy borderlands from a trustworthy key reseller, save like 70 bucks minimum by doing this. Use said savings for something else. Or do what people said here, wait a bit longer and then buy something.

I made my computer build 1 month before the 700 series were announced, and i sort of regret buying my 670 as the 700 series offered better choices and cost less. Like the 760 being nearly the samething as my 670 and it's cheaper.
