Eh, my 2 1/2 year old laptop only shows 2.3. . Video is the factor holding it down. Nothing I can do about that, but it's not a big issue. For my usage, it runs fine with Vista Home Premium and 2GB of RAM.
oh yeah, my laptop (Satellite L300, Dual Core 2.0Ghz With 4GB RAM, Windows 7) get's 3.3; it get's... 5.0 on everything but 3d-graphics, which drag it down to 3.3. On the other hand, it's not 2 1/2 years old; it's less then a year old.
Sad fact is I hardly ever use it; it mostly sits and runs folding@home. I used to use it a lot more when it was better then my desktop, though.
