My 8800gt is consistently running btw 95-105 celcius. I've already taken it apart, cleaned and added AS5, but without much effect, except the fan runs quieter now. So - I plan on building my new rig when Battlefield 3 comes out, but I want to get a gpu now, that I can SLI later on. I will probably be building with the new SB ~2500k. I'm most likely getting the Radeon HD 5770, based on TH article, but I don't know it is compatible with my current setup. Sorry, but I'm still using XP and DX9. I want to know how the new gpus work with the different PCI connections. Is 2.1 compatible with 2.0, 1.0 1.0 X16. I don't know the difference. My mobo right now is (Motherboard Name DFI LANParty DK P35-T2 / P35-T2R/S). Everest also says it has (Expansion Slots 3 PCI, 2 PCI-E x1, 1 PCI-E x16). Will this card work in this mobo. My new rig will use Win7 64, I guess DX11. Any info would be appreciated.
As far as I'm aware PCI-e 2.1 is backwards compatible so a HD5770 should work fine in your current PC, Oh and a HD5770 is an ATI/AMD product so it would be Crossfire and not SLI (nVidia). Just install the HD5770 into the PCI-E x16 Lane.
I'm only looking at the 5870 because of the TH benchmarks. Its at the top of the lists, so in a years time after BF3 is out and I have my new rig, doesn't this card make sense, or are my eyes bigger than my mouth?
Yeah a HD5870 isn't a bad purchase now as you could carry it over to your new build, and there quite cheap now. Never heard of Nspire before, I personally wouldn't trust a PSU brand I've never heard of before, I'd always recommend going with a quality brand like Corsair, Antec, Enermax ETC....
The PSU should have a sticker on it somewhere, and on that sticker it should tell you the max wattage output for the combined +12V rails, could you tell us that info?
