yeah, well pretty much the only reason I wanted to overclock the CPU was so that the GTX 260 was not bottlenecked. I dont hear about the 4870 getting bottlenecked from lower CPU speeds. Does it? Because If it is only the case with the GTX 260, then overclocking really would serve no purpose... I've read reviews and the 4870 is nice but I just get a funny feeling about it. Care to enlighten me?
They perform at around the same level, so if there's a CPU bottleneck with one, it'll be present with the other. However, CPU bottleneck's are usually only a problem at lower resolutions (~<1680x1050 in the 260/HD4870's case)
As for your funny feeling about the HD 4870, there are lots of happy GTX 260 owners (apart from the people who bought them when they just came out
) and there are lots of happy HD 4870 owners. There's nothing wrong with either cards is what I'm trying to say.
I looked at some reviews of the 4870 1GB vs the TX 260/216 896MB and "Overall, it seems NVIDIA's card doesn't just excel in performance, but in both power consumption and temperatures as well."
If you're reading any review showing one excelling
over the other, then you're reading a biased review. It depends from what angle you look at it, but in 99.99% of cases:
HD 4870 512MB = GTX 260
HD 4870 1GB = GTX 260 Core 216
