I have just upgraded to a 5870 and think my cpu may be a slight bottleneck. it is a e8400 running at 3.6 what do you guys think would be a worthy upgrade for me.
 
Clocking it to 4 ghz :)

Otherwise you want to look at q9550/q9650, but unless you're on good cooling and motherboard it won't clock as high as the e8400. For anything that isn't loading more than two cores, the slower clocked quad will be slower.
 
There are very, very few e8400 processors which wont make it over 3.6 ghz. If you can't take this one over 3.6, you won't get a q9650 near 3.6. I suggest you stick with what you've got.

Or, ideally, find out why it's not making it past 3.6.

^could be board/ram/cooling/you that's limiting the clock

And its on water! Whne i say i can't get it past 3.6 they guys who put my pc together said it was only really prime stable at 3.6 maybe i need to try it myself. I'm running a asus P5E board with 4 gigs of ram.
 
My E8500 does 4.5Ghz easily in a P5E so it's not the board holding it back. More like ram divider/CPU voltage or lack of a decent cooler maybe.

What ram do you have? 2x 2Gb sticks or 4x 1Gb sticks? C0 or E0 stepping E8400? I think i still have my settings written down for my P5E somewhere.
 
If you have a water cooled e8400, in a P5E, with two sticks of 1066mhz ram, and it wont go above 3.6ghz, I make that your knowledge limiting the clock. Research it a bit then have a play :)
 
CPU stepping can effect the OC...also check volts(is it getting enough volts) as you are running Water Colled so hi temp shouldnt be much of a problem
 
The faq is an excellent starting point, then googling e8400+p5e+overclocking is likely to work well. Certainly this will let you have a bash at overclocking it yourself (easier than it seems, hardest part is working out what to consider 'safe' voltages), and will let you form questions we can answer usefully :)

It's basically a lot easier (and so more successful) to guide someone who understands the basics, and has already had a go. We're happy to help though, so please don't feel discouraged by this post
