Ok...I need a bit of advice on getting a new video card for my T2240 emachine; All my slots are white/gray incolor....I bought a card but it was the wrong one...what type of card can it take...also whats a good low-end card with, I think it was pixel shading? (have a game that needs it) and one more thing...will increasing my ram help speed an on-line game up? Will I need to upgrade my power supply...and I did by one of those....but....its large and mounts differantly (wont fit inside)...can I hook it up as an external power supply with no problems?
