I'm looking to upgrade my graphics cards from 2x5770 in crossfire to a 7870 and or possibly 2 of them in crossfire. My Mother board is designed for crossfire by gigabyte, I think I have a great build overall (for its age), but looking to stretch it as far as I can without having to spend money building a new computer at the moment.

My specs on the PC are as follows: E8500 overclocked to 4GHZ, 8GB RAM 1066Mhz clocked down to 1000 to have 1:1 ratio with the FSB of the CPU (again any mistakes on my part please forgive) 2x5770 in crossfire - system stays pretty cool. The PC has its hicups once in a while, while playing games....that may just be because I'm running two different videocards made by diff manufactuerers....:P

I'm havnt been keeping up with the whole computer hardware scene and looking for some input on any issue I may run into or if its even worth upgrading the video cards running an OC E8500....

Thanks in advanced!

e8500 is too large of a bottleneck for any new gpu

I'd have to agree I upgraded 2 years ago to the 2600K from an E8400 at 3.6 ghz because of bottlenecking issues. When I switched I gained about 30 FPS playing RIFT.

A single 7870 won't be much of an upgrade (or it is you have the xt version) and you will have better overclocking options. 2 7870's will show bottlenecks but not only that some games do benefit a lot from more than 2 cores. With your setup , I would suggest to sell your system and just buy a new one.

Don't bother.

With that setup I'd change CPU/MB/RAM first, then GPU. Or if it's a good mobo get a used C2Q and overclock the sh*t out of it. E8xx is definitely a bottleneck for 7870.

i had an E8400 and i found it even bottlenecked on my amd 5870. That gen of cpus is excellent but its only 2 cores with no hyperthreading either so it leaves no room for anything. i had mine overclocked to around 4.0 ghz but even that didn't help much. so get brand new pc if your gonna upgrade... you can't put in a video card that powerful on a cpu thats 5+ years old... even if that cpu was excellent for its day.

depends on the game if the E8500 would be a bottleneck or not , if a game only uses 1-2 cores then it shouldnt be an issue with a 7870, however the majority of newer games make use of quads and those game would see a cpu limiting factor. Also running two 5770's is more of a bottleneck then a single 7870.
