SVD_Sniper;3902471If my PSU is not up to scratch, will the card simply not work? Could I remove my soundcard to free up some power (reduce total energy input required) ? Failing that, would I need to buy a new PSU as well?
Also, Ive found several different cards called the 8800, is this one still good? OcUK GeForce 8800 GTS 320MB GDDR3 HDTV/Dual DVI (PCI-Express) - Retail
I forget exactly how it reacts when it is power starved, but it isn't recommended. Removing soundcards, HDDs, etc won't make much/any difference. If your PSU is real close to the minimum, it's suppose it's worth a shot to try it. If you do buy a new PSU, many £30-£40 units would be more than adequate for any single video card.
Pretty much any 8800 card you get is going to kick some serious tail. If you aren't gaming at high resolutions (1600x1200 or higher) than just get the 320mb card. The 640mb version wouldn't perform any better at lower resolutions. Also, the money saved by not getting a 640mb version would easily pay for a decent PSU. Good brands to buy could be XFX, BFG, EVGA & Gainward, to name a few.
