<i>Hi ...
Can you guys assist me. Is the Chaintech GeForce4 Ti4200 good brand?</i>
I've heard good reports on this specific card. Go for it if you have the money!
<i>Which one should I go with? Chaintech GeForce4 TI 4200 or Visiontek GeForce4 MX 440 for game.</i>
Chaintech GeForce4 TI 4200 definitely. MX440 is going to be about 30% slower and doesn't support DirectX 8.1, only DirectX 7.
<i>Does it make a lot of difference with 64MB DDR compared to 128MB DDR?</i>
Yes, 128MB gets you higher framerates in games that use lots of textures. If you want a longer life for this card you are about to buy then get 128MB or else if you plan on buying a new card in a year you can be safe with 64MB.
This little cathode light of mine, I'm gonna let it shine!
