No. You just don't want to spend a million dollars on a GPU if your CPU can't compete.

Great cooling for only 50 bucks. Side 80mm fan was broken though. :c I sent them an email. Hopefully they can send me a new fan. Anyway, do you think I can fit a 6950 in this thing? My borked 4850 seems to fit with plenty of room.
It should TBH.
I'd like to know if buying a laptop dock would be worth it.
I wanted to get a dock specifically for getting a better video card without potentially screwing up my laptop beyond repair, nothing else. I'd only use it when I'm playing stuff that tends to slow down, like Audiosurf (recently atually), Minecraft, and Blockland on certain servers.
Dell Latitude D630 (might be D630c?); WXGA+
2GHz Core 2 Duo T7250 (obviously upgraded, it apparently had a Centrino before I bought it)
2GB RAM
I'm not sure about this, but 384MB Intel GMA 965
Windows 7
They come with Core 2 Duos, so it wouldn't have been updated.
Also, yes you can get a dock, but IMO it's really quite complicated and not worth it. You spend a lot of money, the bandwidth is severely limited so therefore the performance isn't that good, then you've got power to worry about, and also the fact that your laptop HAS to have the right expansion bay.
