Scored an average of 442 on their list. Want to be scoring at least in the 700-750 range to stand a change of consistently hitting 25FPS or better. When looking at your options, you can browse their lists or use their search engine (just plug in the number and it will suggest cards it has in it's list: type 640 and it will list different ones, click the GT640 to see it's stats):

Okay thank you!

Edit: Okay I checked it a bit now, the problem is I have an "ESPRIMO E9900", on their data sheet I found out the mainboard type (http://globalsp.ts.fujitsu.com/dmsp/...900-EStar5.pdf)
I still don't know what kinda graphic cards I can use...
I mean it's not like I could just buy myself one and use it then, right?
