lets wax philosophical here for a bit. linux is less bloated than windows and uses opengl instead of the ruthless dx. we "should" see better gaming performance on a linux platform spec for spec than on the windows platform so long as the same effort goes into the opengl drivers as the dx drivers. that being said, and with the consideration that at least for the next year the games supported by steam for linux will not be gpu intensive, a think a nice linux gaming rig includes a slower i5 chip (3330?) and perhaps something like a gtx550. dual channel ram is fine at 1333 (4 gigs?) and throw in a 256gig SSD for good measure i think you have an inexpensive yet very responsive linux gaming rig for the next 2 years. what do you guys think?
