If u keep in mind that the human eye only can see until 100 FPS (a little more or less) 300 FPS only can useful for benchmarks
Now if u still want the i7, I'd go with an i7-930 plus a ASUS P6X58D-E or ASUS SABERTOOTH both are very good mobos.
i know but its like owning a Ferrari you'll never go that fast but everyone is like damn... :P
uhh forgive me for sounding like a noob but i just don't understand this part of the specs
"PCI Express 2.0 x16 3 (@ x16/x8/x8 or x16/x16/x1)"
i know it's for the video card but how do i know what im looking for :P
