ok is there any chance of you having a cpu upgrade cos it would be a serious bottleneck if you stuck an 8800 in it. If you get a E6750 and overclock it to around 3.5 ghz and get an 8800gt you will have a very good system capable of playing anything you throw at it.
Should be able to easy, AMD's website says it needs 550w minimum psu for Crossfire system with the 3800 series.
The 3850 256mb version performs on average almost twice as fast as the 8600gts. The 512mb version is supposed to be able to hold up decent performance in most games at higher than 1280x1024. The 3870 should also work in your system. You could probably run the 8800gt as well, without much problem from the PSU.
Now if you want to wait for what looks like a good card, that I think it's sapphire? vapor 3870 looks interesting.
Your proc will be a slight bottleneck. Can the board handle a 1066 based processor? c2d e6400 or around there wouldn't be bad.
yes, i was only bothering about that cpu, it is quite old. yes it can support 1066mhz processors! but, i had a topic elsewhere, where i asked wich cpu my asus p5ld2 could handle! i only have an 17 inch syncmaster 740bf, so higher than 1280x1024 is not an option, so that 3850 should do well?
i was only talking about that 3850 because i thougt i was risking something with that 8800 and 3870, because they are greater and stronger than that 3850, and i thought maybe the 3850 will run on my system.
i can get
Sapphire ATI HD3850 - 512Mb - PCI-X: 512MB,PCIe Active,Tv-out,2xDVI-I,,GDDR3, productinfo
I'd get the HD 3850 because it's cheapest. Anything more is a waste for this build because of the CPU bottlenecking.
In December, or whenever, you can sell it or reuse it or put it in a second slot to use for a separate monitor, or try Crossfire. I read somewhere that ATI will get Crossfire to work even with different cards, so maybe you'll be able to combine it with a newer card.
That 1gb 8800GT is nice, but it's pointless at 1280x1024. Lots of video RAM are really useful at the huge resolutions. I don't know for sure but I'm guessing it consumes only a few watts more than the 512MB version.
