Hi,

i´m buying a new 24" 1920x1080 lcd screen (upgrading from 19") and of course there will be some performance loss.

I was thinking about buying another HD5770. Would my CPU bottleneck 2 hd5770s in crossfire. My specs are listed bellow.

Also is it worth upgrading or should I just buy a new computer in about a year? My pc is already more than 4 years old...

C2d E6550 3.0 ghz
4gb ddr2 ram
HD5770 1GB
1920x1080 24" screen

What motherboard and PSU do you have?

At 3ghz their will still be a slight bottleneck but nothing severe.I suggest O.C.ing further if possible.It's worth upgrading to a new CPU.But of course that would mean you would have to buy a new mobo and RAM.

It wouldn't be too much of a bottleneck; not like to the point where it would not even be worth it, but just ever so slightly. What games do you play? (that will give us a better standpoint to make a decision)

His speed will help, but the fact of the matter is - he doesn't have much cache.

It will really depend on the specific game and settings you use but yes, there are a lot of games where your CPU would be the limiting factor in such a setup.

Well your going to have to upgrade your mobo to crossfire anyway so you might as well go for a new build.
