my board cant take E8XXX to 4ghz ...max 3.8...limited to 400(p43ql pro )...i was thinkin to buy used Q6600 and overclocked it 2 3.2ghz that wont bottleneck any gpu i think .. ??now i just wana know abt E5300 @3.4ghz
My 4850 bottlenecks my E8500 @ 3.8. The wolfdale is ~ 80% usage during most intense games such as fallout 3 and I can get kinda choppy at certain points. I do believe your 4870 would be bottlenecking, sir.
A E6300 at 2.8GHz (same as a E5300 OCed to 2.8GHz) somewhat bottlenecks a 4890 in certain games according to Tom's balanced PC review.
A 3.47GHz E5300 should have no problem with a 4870 or a 4890 for that matter.
