no. basically there are only two variables:

1. slot type

< 4 years probably pci-e

> 4 years probably agp

> 4 years + low end motherboard and not agp = pci (bad news)

2. power supply

low end cards < 400watt

High end cards > 450 watt

very high end cards > 600 watt

Thats all there is to it. Determine your slot type and power supply and you're in business.

cpu-z or belarc advisor will tell you slot type

Your power supply should say on it.

Find a reliable PC Forum and post your computer specs. They will give you your answer.

The most important factor will be a power supply though.
