OC'd E6750 ... when to upgrade?

[Snubber]

I'm running an OC'd E6750 at 3.2GHz. Just about to upgrade my gpu to a 5850. PC is used mostly for gaming, no video encoding or anything like that.

From the benchmark comparisons I've seen it looks like there's not that much performance gain from the new crop of CPU's.

How long should I be able to hold off from having to upgrade CPU and mobo - 12 months?

Thanks,

For me I'd say now as I've just gone from my E6750/8800GTX to 955BE/5850 for a little over £400 as I recycled my old RAM, HDD etc and its quite phenominal.

I put my 5850 in my E6750 rig for an evening before I droped the quad in and it was a substantial upgrade going on the BF:BC2 beta. Since installing the quad its far far better and then some more, in desktop web browsing etc it seems the same but installing games/ programmes / windows, unpacking files in winRar etc theres a definate inprovement.

Plus it's more more energy efficient , if you care about that.

Yeah...thinking about almost the same upgrade but with a 965BE rather than 955BE - worked out as a net outlay of £300 after selling current GPU/CPU/Mobo. Or could keep existing mobo and go for a Q9550 that gives same performance as the 965BE. Seems to be a pretty sensible, high vfm upgrade for £300.

More games seem to be coming out which appear to love quads
