Upgrading my graphics card?

[crisosphinx]

If you get the 6 gb of vram, version, then your powersupply should be over 800 watts (counting in RAM, processor, motherboard, disc drives, etc.), I'd assume.

Even if he could get a 6GB GTX 660, he shouldn't need more than 550 watts.

Well, like I said, including RAM and such. I also screwed up. I mixed the nVidia Tesla 6gb with the nVidia GTX 660 Ti 3gb. My bad about that bit.

I'd assume with a GTX 660 + at least 16gb to compliment it nicely and I'd assume he has something between a 4-8 core computer (plus if he had two monitors and never unplugged them), you'd want at least 800, especially if you run it on Max SSAO, AA, (and all other highest graphics quality). For example, and this happened recently, my girlfriends computer busted her supply due to her over powered system AND she elected to play BF3 (yeah, I know, that's WAY more intensive than Amnesia, but still).

Then again, I'm assuming he has a stronger computer, PS is probably good enough. I was just suggesting to check into it.
