The Best bang for the buck IMO other than the Radeon HD 4870. (128bit vs 256bit, DirectX10.1 vs DirectX11, I ended up getting the HD5770 because of the Tessellation of the DirectX11 sacrificing the 256bit, I did plenty of research on what to get, this card is by far the best for it's worth, get 2 for Crossfire and see this go against the 5870.

Cons: Uses 2 Slots (I don't mind it)
Other than that, no cons.
I haven't had this long enough to see the possible cons.

Overall Review: My Mid Tower has limited amounts of Vents and Fans, but the Video card still seems to stay under 80C and for me that's good since I've experienced my ATI Radeon x850XT running at 100C and would still work normally. I think anything under 90C @ Load would be considered "cool".

If you're thinking of Overclocking a video card and you're not a guru at it, please don't attempt. Just like an engine, if its not meant to be ran any higher than the rated Horsepower range, then it's actually going to damage the components. Heat = damage. So running a video card beyond its normal Heat tolerance will shorten its lifespan and eventually kill it (R.I.P. x850XT). If you still want to Overclock it, know the consequences.

My Rig:
Using an AMD Athlon 64 X2 4600+ (2405 Mhz), 1024MB x2 of PC2-6400 with 512MB x2 of PC2-4300 (total 3072MB), AsusTek Motherboard NODUSM3 nForce 410/430 MCP, 600 Watt Raidmax PSU, HP Pavilion a1747c Casing, and the Sapphire Vapor-X Radeon HD 5770. (I salvaged this Compute

Pros: Played games decently.

Cons: No PhysX support, or CUDA. Like all AMD products I've owned they run hot and don't last.

Overall Review: None
