This is similar to my main PC (which I use for video encoding and HD video playback), where my PC is a 64-bit Intel Core i7 920 w/6GB (Asus P6T Deluxe V2 motherboard) w/ PCI-e nVidia GeForce GTX260 graphics. I am running openSUSE-11.2 on it with on problem. Previous 11.1 worked on it. I booted successfully 11.3 M7 on it.
I spend a bit extra for the power supply, but I dont know it off the top of my head, … I have to look it up. I think it had a bit less than 550 W, but I’m not sure.
Well CUDA is already there, I use it on occasions with this card. I
always install the ‘Hard Way’ so it would pay to keep a copy of your
xorg.conf around as it may be needed since sax is/has gone.
You might even consider SATA SSD for the OS and then use a 10K raptor
to process on. The other option is RAID0 which will give a perfomance
boost but no redundancy. I run 2x36GB raptors in RAID0 for the OS and
have a WD 500GB RE3 for data and configs, then a small NAS with 2x500GB
RE3’s for backup.
If your processing for long periods of time at full load, then I’m not
sure about the i7 maybe you should look at googling on that?
