Possible CPU bottleneck with HD 5830?

[Cyclops]

Hey,
I'm in a fix to choose between HD 5770 and HD 5830. Among other factors, one that i was wondering about is if I'd be able to extract the maximum performance from HD 5830, if i choose that, given that my CPU is AMD 5400+ 64 X2. Would there be any case of CPU acting as bottleneck if i go with 5830?

My relevant system specs are
AMD 5400+ 64 X2,
4 Gigs of DDR2800,
Thermaltake 750w PSU

one more thing, I'm running Windows 7 64bit OS

So you're saying that the difference in performance between 5830 and 5770. as shown, by the reviews would be far less in the case of my system?

Yes because most new systems that are being benched with 5770's and 5830's are running quad cores @ anything over 3Ghz. In other words if you want to spend your money wisely you would go with the cheapest 5770 money can buy and with the change left-over you can get an x3/x4, instead of buying a 5830 and using your current CPU

I assume this is what ct meant

I think the point is, the AMD 5400+ CPU is going to start becoming a limiting factor for you. So rather than spending the $70 difference between a 5770 and 5830, use that money to help fund a CPU upgrade. Overall, you'd probably see a better performing computer. In and out of games.

I think OvrClkr's point though was to realize that you won't get the performance you're expecting from the 5830 or 5770 (simply because all the reviews/benchmarks are done with much better CPUs than what you have). So any FPS benchmarks you find on review sites will be fictitious when compared to the same card being installed in your PC.

Now, if you could afford the CPU and 5830, obviously that'd be the best performance. But at that point, one has to consider stepping up to the ATI 5850. So really, if you're playing 1680x1050 resolution or lower, I'd get a newer CPU and the ATI 5770.
