I currently have a Geforce 8600GT 256mb DDR3 connected to a 40" HDTV. I'm looking to upgrade and my goal is to be able to run MW2 at 1080p and to be able to play 1080p mkv videos. Currently I can only play 720p video files. I want to spend around $100.
I've been looking at the Radeon HD 4770 512MB 128-bit GDDR5 card from Newegg for $109, but I can't decide if it'd be better to go with a 1GB DDR3 for a 1920X1080 resolution or the 512MB GDDR5? Will the 4770 be able to handle MW2, or is there a better option?
