Graphics Card - BFG 896Mb nVidia GeForce GTX 275 OCX PCI-Express VGA Card

I am hoping after a few months to run a second one of these graphics cards in sli.

I will be using my 22 inch Benq monitor and will probably buy a copy of windows 7 home edition 64 bit for this setup.

I would really appreciate some advice and opinons on this build, maybe some compatibility information and different ideas instead of the components i've chosen such as the graphics card as i know theres such a wide selection out there. Also if i should look into any additional cooling.

Thanks for taking the time to read this, il look forward to the feedback.

everything else the same

obsidian86's builds are all-around better builds. I would highly consider the Intel build. My work blocks access to www.ebuyer.com, but I don't see a CPU listed in the first build.

I chose that psu because i was going to hopefully run 2 of those cards in sli eventually and i have noticed people prefer intel builds and the ati cards such as the 5850, i am from the uk but converted i have about $1200-$1350 to spend on my new build. Im mainly going to be using it for gaming so id like to hear any other setup ideas aswell, thanks.

Hi, thanks a lot for everyones help, i am going to go with the 5850 and the AMD phenom 955 and i will build around DDR3 as suggested. So im basically going to go with what obsidian86 listed in the first post apart from the motherboard.
