Will E8400@4.0Ghz bottleneck HD5770 xfire?

I'm wondering if there will be a huge bottleneck with my overclocked E8400@4.0Ghz running HD5770s in crossfire? Most of the benchmarks I've seen are run with an I7 and DDR3 memory. Anyone running crossfire with a C2D anymore? I'd much appreciate any input on the subject.

I will be gaming at 1920 x 1080 res if that helps anything.

Thanks in advance!

only in a few games such as GTA 4 and Dragon Age would there be any noticeable advantage having an i7 over your E8400 at 4.0. really for almost everything else you will still be gpu limited with the right settings. I would certainly go with an i5/i7 before your next big gpu upgrade though.

I plan on doing a complete overhaul in a year or 2 when I7 and DDR3 come down in price. I try to stay 1 or 2 years behind the curve to eliminate early adopters syndrome and buyers remorse. I got a decent deal on an HD5770 for $150 and I think adding another would be enough to keep me gaming happily for the next year or 2.

I am mostly concerned with games and apps moving rapidly towards multithread and my E8400 taking a hit because of it. I'm also taking into consideration that crossfire scaling on an I7 platform is probably notably better than my C2D leaving me with high expectations that might not get met.

I guess Im more or less wondering if adding another HD5770 should take precedence over
an upgrade to a quad for my gaming needs. I basically have a choice of going with the crossfire setup or swapping my E8400 out for a Q9xxx. By your statements above it seems like the crossfire setup would better suit my needs.

Does this seem accurate?

yes going with another 5770 would be way more beneficial than upgrading your cpu. really with the low price of i5/i7 I dont see the point in waiting forever to upgrade the cpu though. i7 has already been out for over a year so your early adopters paranoia should have subsided. really in 2 more years i7 will have already been eclipsed.

Well its not the paranoia as much as the cost that makes me and my poor wallet cringe. The only reason I'd considering a quad core would be for gaming. I dont think I'd even need a quad for anything else.

I7 860 = $250, motherboard = $100, 4gb DDR3= $100 total= $450 to upgrade to a system that would show me little to no noticable benefit while gaming at my resolution. There are so many new innovations coming soon that I would rather spend my money on. 600mb/s SSDs, Sata 6.0, Lucid Hydra, hex and octo core CPUs. I feel like I'd be much better off saving the $450 until atleast next Christmas.

Thanks for helping with the bottleneck question, and giving me some things to think about hehehe...

well you need to factor in selling your other stuff as that would offset some of the cost too. yeah just stick with that cpu for now and then give it about a year or so and see where things go.

I haven't seen a convincing case to get anything other than the e8400 if your primary concern is gaming and you're using high end multi-GPU. I know some tech sites have argued otherwise (including this one, I think), but it still seems as if a pumped dual will suffice at least until the next gen of CPU's. There are some exceptions. If I recall, the Dunia angine in FC2 seems to respond well to tri and quadcores.
