What CPU to get for a 5870?

post #1 of 15
Thread Starter 
Hi, I'm currently planning to make a massive upgrade to my system. I'm going to be buying a new motherboard, CPU, RAM, possible an SSD and PSU depending on budget constraints. My birthday is on March 25th and I'd like to get something that won't bottleneck my 5870 like my current CPU. I'm running 1600x900 resolution screen. I'd like an Intel CPU if I can help it, but I'm open to any other options. Thanks you.

Well you would probably be fine with a duel core, but get the new sandy bridge. One key to not bottleneck it is to get and higher CPU overclock.

the 2500k should be fine. Heck even a Phenom II 955 would do the job

2500K is one of the fastest gaming processors out at the moment. Good Solid Choice.

any of the i7 processors from intel, or x6 from AMD will be fine.

Just upgrade the CPU in your current rig for the moment.

It doesn't make sense upgrading a full rig until Bulldozer has been released to see how it performs compared to Intel's SB.

According to the Asus website, your mainboard actually supports pretty much all of AMD's latest CPUs, so on a budget, just slot in a 3Ghz Athlon II X4 640 for ~$100 and you'll be right to go.

From reviews I have read, the 640 actually performs pretty good - matching AMD 1090t in pretty much all games.

It also has no problems with a 5870, almost all reviews used a 5870 and if the 640 matched the 1090t for fps, you can be sure the 640 is no more limiting then the 1090t, which is not that limiting at all

You're lucky your mobo supports most recent CPUs, a ~$100 CPU you can slot into your existing rig is much cheaper then building a new rig with a 2500K.
