this chip would be a good step up from Xenos/RSX, but by todays graphic cards offerings it's low end
for comparison, the E6760 is almost the same as the GPU on the Radeon HD 6670: http://www.amd.com/us/products/desktop/graphics/amd-radeon-hd-6000/hd-6670/Pages/amd-radeon-hd-6670-overview.aspx#2
both have 480stream processors but that one is clocked at 800MHz, so it does 768Gflops, while the E6760 (at 600MHz) does 576Gflops
the HD 6670 card is about as good as the HD 4850 in the comparison I found (it largely depends on the games used in those), but as I said the E6760 clocks 25% lower so expect it to be perform a bit less than that
