Hi guys! I've recently been contemplating on changing my GPU. It's an XFX 9800GT and holds its own quite well when using DX 9. I'll be switching to Windows 7 sometime soon and would like a new GPU. For all purposes, the Radeon HD 5850 will be beyond my budget. So, I've narrowed it down to 2 cards: Palit GTX 275 or PowerColor HD 4890. Most of the reviews I've read seem to put the GTX 275 on top. However, I'd like to know whether the newer Catalyst drivers have upped the performance for the HD 4890. Both cards cost about the same here. Which is a better performer in terms of raw FPS, power consumption and temperatures? I must mention that I'm running an AMD platform with a Phenom II X3 720 and ASUS M4A78T-E. My PSU is a Cooler Master Extreme Power 600W which I intend to use for now. That's why I'm concerned with power consumption. Any inputs are greatly appreciated. Thanks.
