The fan on my XFX Radeon 4890 died and I didn't keep my receipt so I'm not able to RMA. Aftermarket fans are pretty scarce but can be had for around $50-60. There is currently a deal for the Sapphire 7770 for $75 after MIR which I am tempted to get since it's just a little more than the price of a new fan. Benchmarks are comparable or slightly better than the 4890 and the power usage is significantly lower. The only games I play occasionally are L4D and L4D2. Other than that, I mostly use my PC for running WMC with a SiliconDust HDHomeRun Prime. It's a Core i7 with 12 GB RAM. I am also driving a 30" monitor. Can anyone let me know if this is a suitable replacement or if I should be looking at another card? I'm not looking to spend much more than this price. TIA for any input!
