Hi, I just built a new system using a HIS Radeon HD 7850 1GB version. I've noticed some really bad screen tearing/very large amounts of fuzzy lines across the screen on the games I've been playing, like Call of Duty WaW, Battlefield 3, and Starcraft 2. Now, in-game, I've been enabling V-Sync, but that doesn't completely fix the problem, and it really kind of destroys the frame rate. On my old build on the same monitor, I've been using a 6850 and there was no screen tearing at all. Is there an easy fix for this, or do i just have to live with it? On a quick google search, I found that some people found success from using a DVI cable instead of using a VGA cable and an adapter, which is what I use now. I am in the market for a new monitor, so buying a monitor with native DVI support wouldn't be too much of a problem, but I want to make sure that it will fix the problem. Here are my full system specs:

1366 x 768 monitor with 60Hz refresh rate

HIS Radeon HD 7850 1GB

Intel Core i3 2100

ASRock B75M-DGS

Corsair 8 GB 1333mhz ram

Western Digitial Caviar Blue 250GB hard drive

Corsair 500 Watt PSU

Thanks for the help!
