Hello, I need to upgrade video card of old desktop PC. I tried "PNY NVIDIA GeForce 6200 256MB DDR2 AGP" graphics card. I'm looking for a new or used card BETTER than above "GeForce 6200 256MB" which is : 1. AGP 2. Economical - below $50 (I understand it means that card might not be of current generation) 3. Should have 3D Accelerated Video with 256Mb (512MB preferred) dedicated video memory & Pixel Shader 3.0 support. Is "PNY NVIDIA GeForce 6200 256MB" card BETTER than ATI Radeon 9600 and NVidia Geforce Ti4200 ? By how much ? I saw this card "Visiontek Radeon X1300 XGE 512MB AGP DDR2 Video Card" at: http://www.buy.com/prod/visiontek-r...directx-9-video-card/q/loc/101/209199998.html. Please compare it with "PNY NVIDIA GeForce 6200 256MB" ? Please also suggest new/used video cards, meeting 3 criteria. Thank You.
