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.
Is this too much card for my system, or am I going to see lots of improvement? I know that my DX9 will hold something back, but how much?
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?
