To be honest, if you want to compete in 3d benches you need high clocked cpus. If vantage, a hexacore will dominate. In older benches like 01, high clocked c2d will pretty much be hard to beat. SB is doing well in that area, but before it was just E8xxx chips that were used.
got 6364 marks. in 03
which is about the same as having it clocked to about 570mhz core 365mhz mem and 1134mhz shader..
with the cpu clocked at 3.7ghz
might be able to get a e7400, 2.8ghz stock goto 3.51ghz on a g41 board then fbs cap. so should do alright on this board i guess
