Honestly, I found my HIS Radeon HD 4670 was able to run games fairly well at 1920 x 1080. Sure with the crazier settings turned down, but point being that it was pretty good for the games out there right now.
Point being, I can imagine this HD 4850 would be a pretty solid graphics card for such a low cost if you're wanting to upgrade on a budget. For those interested, check out Tom's Hardware and see how it does benchmark wise.
Thanks for posting OP. Little good to me, but I'd think this a good deal for others with older graphics cards.
