no problem! Glad I could help.
Keep in mind that if you are building a computer now you could still run a mainstream PCIe3 card in a PCIe2 slot. It is just the upper end cards (specifically those with 2 GPUs on 1 board) which will be choked for bandwidth. But if you are not hurting for an upgrade, then wait a little bit until all the new standards get sorted out and become more pervasive in the new systems (PCIe3, USB3, SATA3, thunderbolt/lightpeak, and WiDi just to name a few). But if you need to upgrade now like I just did, you won't be disappointed.
