I've always been a avid gamer since I was 13 playing whatever the game may be. Currently I play Darkfall Online which is very intense on my rig I get low 20's on my frames during big sieges just looking to upgrade some things mainly my GPU, Mobo, Ram. Please any suggestions or help would work.
is it really worth upgrading to one of those cards over my 4850?
My budget also for a complete overhaul and or rebuild would be about 600 or so.
^ Unofficial sources point out that June would be the launch of the new AMD CPUs, so I would suggest you hold on till then,...And yes the current cards would perform very well when compared to the 4850,...
