Replacement for gtx 260 sli

[mcalc55]

hey guys..selling my 2 evga gtx 260 in sli and looking for suggestions to replace them for all the latest games coming out. How concerned should I be about CPU bottlenecking with my first gen i7? These are my current specs...I'll get between $110-150 for the cards which would go directly to a new one so I"m looking for the best bang for the buck, given that the system is pretty old already

Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz
6.00 GB
2x NVIDIA GeForce GTX 260 SLI
700 Gig 7200 RPM HDD
64 Gig Samsung SSD
Windows 7 Ultimate 64 bit

Thanks
Mike
