as it is now the specs for my pc are this

Athlon 64 3200+
512MB DDR
120GB HDD
256MB Geforce FX 5900

but I'm missing the video capture card now I'm using the video input from my other pc the I use a geforce2 MX400 with VIVO, now the only prob is that the HD is limited to 13GB I'm recording trough the other pc and then transfering it to my Athlon 64, and it is quite annoying.

I'm gonna get the new nvidia card in few weeks for the Athlon 64 computer, should I get that card with vivo or should I get a video capture card separate?? which is better quality??

and also what is the best ammount of ram I can use??

Thanks
