im trying to have my desktop out video to my 42in plasma. which video card would be able to handle that. ive been through two cards from best buy and they both sucked. i didnt buy the cheap ass cards either. one was $90 and the other was $150. both gave me choppy and blurry resolution. please help me satisfy my computer porn mega fantasy! card has to be for agp slots also

thanks

ps im equals the suck ass when it comes to computers.
