So I need a new video card for some moderate gaming, and some TV out stuff (my ATI x600 is shot and old).

I've got a PCI-e X16 slot. My motherboard will not "support" PCI-e 2.0 though. I've heard that the formats are backwards compatible though. One thread I came across suggested that a 2.0 will run at about 95% perfomance in a 1.0 slot, so better to get a 2.0 card even if your mobo isn't 2.0.

Should I spend for a PCI-e 2.0 or just stick with 1.0? Also is 2.0 100% compatible with 1.0 or about 95% compatible.

Here's some hardware info:

MoBo- Intel975BX
500 Watt PS w/PCI connector

Looking for:
Need S-Video out
Prefer Nvidia (I never really cared for ATI's drivers/software)
Needs to play Dragon Age: Origins

Thanks All!

Yes it will work
It means 95% compatibility because some old VIA chipsets with pcie 1.0 didn't work with pcie 2.0. Also the newest pcie 2.0 GPU's won't have the "real" mem. bandwith, it will work on a little lower bandwith

As for the GPU:

EVGA 896-P3-1255-AR GeForce GTX 260 Core 216 896MB 448-bit GDDR3 PCI Express 2.0 x16:

- if you prefer Nvidia

1 - TV is a 42" Sony Bravia, full HD 1080p/120hz. I'm looking into an HDMI out, TV has no DVI in. Currently I push s-video/composite over cat 5 baluns, looking at upgrading to HDMI baluns, $$$ though and need 2 cat5s...

2 - CPU == 3.0Ghz Core 2 Duo.

And In case it comes up 4GB of RAM.

Also anyone know a good radio (not IR, TV = downstairs, PC = Upstairs) remote control that interfaces well with Windows media player? I still use an old Remote Wonder II. I'd like to be able to fast forward and rewind movie files.
