XFX Radeon HD 4850 1GB DDR3 PCI Express 2.0 x16 CrossFireX Support Graphics Card HD-485X-ZNFC

Pros: - Cheap. Got it for 47 bucks after rebate.
- Cool (46 idle, 70 load on my system)
- Performance/Price is amazing

Cons: This is not a proper desktop 4850. First of all Windows recognizes this as Mobility Radeon HD 4850 (initially, since it becomes "Radeon HD 4800 Series" after installing CCC. Second, GPU-Z lists the GPU as M98 (instead of RV770 like it does with my ASUS 4850). M98 is the codename for Mobility 4850. This is not mentioned anywhere on the box.

This tends to create driver issues. For example, I'm unable to use ATI Overdrive with the latest (11.2) Catalyst drivers. The sliders keep on resetting. However, if I use the drivers on disc Overdrive works fine. Unfortunately the drivers on that CD are based on Catalyst 10.6, and this is a frigging graphics card so using old drivers is a big no-no.

Overall Review: XFX website says this card is not HDCP compliant. Not sure how accurate that is, but if true it would make this card less attractive than other *proper* 4850s.

Pros: cheap

Cons: tricky to get to work

Overall Review: So like many of us, I was having problems updating the drivers for this card. Every time I booted into windows, it would cause an immediate crash. Called XFX, they said there was a BIOS update for the video card itself. They sent me this link:

I downloaded the USB version, created the USB bootup drive per their instructions, flashed the bios on the video card, and now it's working. No more crashes. Hope it helps! Spread the word.

I was about to throw this card out too!
