I'm building a rig for a friend of mine that he wants for lan parties. He doesnt want to much power so im thinking of going with a 9800GTX w/ a core2dua E7500 (newegg link) but i want to make sure that its future proof for him so that he can SLI in the future two 9800's. I was wondering if an E7500 would bottleneck two 9800GTX's in SLI? If it does then what processor should i get so that its not overkill for simply playing games along the lines of Left4Dead, CSS, and starcraft II (when it comes out obviously)?
