I have an Athlon XP-2400 processor, 512 RAM and a Gainward GeForce 3-TI200-128 Mg. video card. I want to upgrade my video card to achieve greater frame rates in flight sims and military action/RTS, Racing games. No frills, no vivo, no TV out, no DVD software, no bundled old games, NO EXTRAS -Just faster frame rates ! How would you rate a GeForce 4 TI4600 upgrade ? What % of frame rate increase would you project with this upgrade(10%,20%,etc.)? Any recommendations for a manufacturer or model ? I want to spend between $ 185 and $ 210 from a reputable on line retailer. Thanks for your help.
