Hi, I have some doubts about professional cards, I'm starting to work with CAD applications but I am using a gaming card (AMD HD 3850 512MB), it handles fine when working in 2D, but I've read that some heavy works (such as rendering) will need a professional one, well, I was looking at the FirePro V4900 1GB and realized that the bus is PCI-e 2.1 x16 but my motherboard (Gigabyte GA-P35-DS3L) has just a PCI-e x16 slot, I am afraid that some incompatibilities could occur, someone knows if there are incompatibilies about using a PCI-e 2.1 x16 card in a PCI-e x16 slot?
The render most likely uses cpu only. Before you buy it I would suggest you try a render as what you read may not be the same situation for you. Your pcie is version 1.1 but works with 2.1.

I was comparing the two cards and noticed that the differences are not very big, well, I don't know deeply each specification, but what's the real benefit if I replace my HD 3850 512 MB to the V4900 1GB? I've read something about a tweak driver that let the gaming VGA working as professional ones, has anyone ever tried it? Thanks for any explanation!
Really the only difference is in viewports. http://www.youtube.com/watch?v=b0BJsagOowg You said the 3850 already handles it fine so may not even do anything. What renderer do you use?
