Okay guys thanks for the input on Video Cards. I posted a thread about it and received some good feedback. I also have like XFX for a while now. Sometimes the prices are just a bit to high. But not as high as Asus'.
I heard that MSI and Asus have better overclocking software though!? Is this true? I was informed that I could also flash the BIOS on pretty much any 5770 bios chip to ther MSI or Asus BIOS... So I may try that.
And usually an XFX card will resale for 20$ or more over other brands...you will make the premium you pay on the card back and i know if i buy a card used i generally won't touch anything without a warranty unless its a deal that i can't pass up
As for GPU overclocking DON'T touch the company software...there all just botched together apps and you should be looking at using either Rivatuner/Ati Tray Tools for your overclocking needs
As for bios flashing i wouldn't recommend it...i believe there are other ways aside from a bios flash to allow higher clocks and a bios flash should be a last resort ONLY if you have another ATI card you could use to repair your 5770 in the case of a bad bios flash
If you where to RMA your card and XFX was to repair the card just to find out the card had a flashed bios on it you probably wouldn't get it back
