I have a 8600gt 256 and I am wanting to upgrade to a 9800gt 512. I don't understand much about power supplies, with the 12V ratings and everything, though I gather they are important.
This is my current power supply http://www.thermaltakeusa.com/Product.aspx?C=1247&ID=15... with one exceptional inconsistency on that output chart vs what it says on the sticker of the actual unit. Mine says the -12V is 0.3A rather than 0.8A. Not that I know the difference or know if it's at all important. The page prior to this says the PSU has a +12V of 29A which I think would be enough for this card but from what I have read, you can't just add the the +12V together like that (15A,14A) or maybe you can do that, depending on who I am reading
I'll try to give as much info on the rest of my computer that I can think of. I have a Intel q6600 processor, 4 gigs of ram across 2 DDR2 800 sticks, 1 sata 3.0 hard drive, 3 120mm case fans. I don't know how much of a difference it would make on taking up power, but if it's of any interest my DVD-RW is external with its own power supply. I'm not an expert builder but to my knowledge, everything is roomy, running cool and very stable as is. If anything else I left out, I'd probably know if asked.
My second question, to my understanding a card with PCI-E 2.0 capability will work in my older x16 slot, correct? If so, would it make a big difference in performance?
Third, since I'm not incredibly in the know of historics or upcoming products, what would be a good time to buy between now and Christmas? Will prices drop much more (99 after rebate average) or is there no reason to wait?
that PSU will be ok, and yes you can run a PCI-E 2 card in a one slot, but i would think about getting the 4850 instead of the 9800gt, the 9800gt is well past its sell by date, the ati card is not only faster it has a lot more going for it, unlike the 9800gt
