First gaming PC

That's a crazy amount of RAM, unless you're doing some CAD stuff, or virtualization, you'll be okay with 8GB (Dual Channel) or 12GB (Triple Channel). The 6xx series GeForce cards are out now. Get one.

...how much does this cost?

Prebuilt, I'm sure it's prone to having problems. Sure it's a great rig just be sure there's enough air flow and what not. I can imagine Gateway throwing in two fans and calling it fair. lol

You should build since you can truly customize your computer and save a ton of money since pre-built gaming computer tend to be on the more expensive side of the scale.
If you do build then go for the i5-2500 and then use the money you save getting the 560ti 448 core. IIRC the 448 core is only slightly more expensive then the regular 560ti but the performance upage is well worth it. Oh yeah, the RAM is an overkill like touche said.

Wait for the ivy bridge processors.i5 2570k would be better for you cost/price wise since it's for gaming.
use the excess money on 680 instead(lol i know)
get an SSD for your OS. it's worth every penny.
you still need a casing/motherboard/psu
too much ram. 8 is enough for gaming.

All im gonna say (and this is with love) fuck you :b I was i had that lol I jelly

Just made this on ibuypower in like 12 seconds, basically what you have only cheaper, and you can actually customize stuff you don't want to buy.

Why not build your own computer? For 1400$ you can build a beast gaming computer.

Edit: I'm pretty sure all these parts cost about 700-800$ individually.

For $1400 you could build one with a gtx680 and have the rest the same while still being cheaper. Right off the bat I don't agree with
-Processor Type: Intel Core i7-2600
Gaming? No. Not at all. Hyper threading isn't utilized by games.. rather 99% of games don't use it. Stick to i5 2500[k] k if you plan on ever overclocking. For a few dollars more might as well. Maybe in the future you'll want to.

Building a PC isn't hard. It really isn't. It's like legos. A part can go in only one way.

Overpriced and spec'd completely wrong, but that's what you get for a prebuild. It's alright as long as you don't mind just throwing several hundred $$$ away, though who knows what kind of crappy job they'll do on the thermal paste. That better not be a stock cooler either or they're very greedy bastards wanting to screw you over.

Don't buy prebuilt. Wasting money and the power supply it comes with will be BARE minimum. Order from Newegg or NCIX since you're in Canada.

i5-2500k (You won't use hyperthreading in games at all. K is the unlocked version if you want to overclock, otherwise just go with i5-2500)
Asrock Extreme 3 Gen 3 Z68 Motherboard
1TB Hard drive (WD Black, Spinpoint F3)
8GB RAM cheapest available rated 1333 or 1600Mhz
550w PSU rated 80% Bronze or better (Antec Neo Eco, SeaSonic, or similar)

Graphic card, I would go with a 7850 if you want slightly better performance than the 560Ti. Uses less power and less heat naturally. 7870 is a decent buy as well. Otherwise 560Ti, 570, 6950, 6970 are still decent.

If you were really going to spend $1400 I'd suggest going with a SSD for your operating system and games. You can load things very fast off of them, just follow some basic guidelines to keep the lifetime of it up. I would suggest a Crucial M4 120GB.

You have a lot of possibilities on a case. Corsair 400R, HAF 912, Lian Li and more.

And you don't even need optical drives anymore. You can boot from a USB stick using a tool from Microsoft to convert and format a Windows ISO to a USB stick.
