I just installed my new Club3D Radeon X800GTO RX and the new Antec SmartPower 2.0 450W. But I noticed that my computer seems slower than it usually is, well it is slower. I looked at the video cards system requirements and it says it needs 256Mb of system memory. I have 512Mb but I was wondering if putting in an extra 256Mb memory would help. The only downside is that the 256Mb memory is PC2100 while the rest of my memory is PC3200 @ PC2700 due to the fact that my mobo only supports max. PC2700. This would slow down the memory but would it help at all? Oh and why does the box the video card came in say that the card supports SM3, when it says it only supports SM2.0b on the manufacturers homepage?
