Dell Studio XPS 1647 recommended for gaming?

From what I've heard it seems like the Dell Studio XPS 1647 has good enough specs to play a good number of games. But I want to ask the community who owns a Studio XPS 1647 to give me their opinion on it when gaming on it. Note that I'm well aware that the Dell Studio XPS 1647 isn't made for just gaming. Anyways I'm planning on buying one but I'm not too convince to do so.
I plan on playing games on the Studio XPS 1647 most of the time, but I'm also willing to do other things such as surfing on the internet, homework, etc.. From looking at the specs I believe that it would be a good computer to buy, but having to look at the graphic card (ATI Mobility RADEON® HD 4670 – 1GB) I'm not too sure that I'll be able to play the games I want to play with the graphic details I want to play in. When I say games I mean like Bad Company 2, Starcraft 2 etc.. I don't mind not playing fully high detail, but at least at a middle set detail when playing. So please do tell me what you think when gaming on the Studio XPS 1647.

 

maybe this will help you a bit. Notebookcheck: AMD ATI Mobility Radeon HD 4670

from my POV, medium settings is fine to play, expecially when I'm not in front of my desktop. heavy gaming there, medium to light gaming for my XPS. if you have the money, why not upgrading the CPU to high speed dual core rather than low speed quad core. better for gaming that way.correct me if i'm wrong.

 

I've been gaming on my 1645 (specs in signature), and I will admit to not being a hardcore gamer, but it is performing wonderfully for me! Dawn of War II, Team Fortress 2, Counter-Strike:Source, Portal, and Stalker have all run perfectly for me thus far. Clearly these are all older games, but I run them at full res (1920x1080) and high details.

 

It's a pretty good choice for gaming. Most games only use 1 or 2 cores (but there are exceptions), so it's probably a better choice than the quad core 1645. Playing the Starcraft 2 beta on my i7 720QM 1645 gets pretty good results (and I would imagine the 1647 would be even a bit better)

For resolution 1920x1080, playing with gpu settings on high and cpu settings on ultra (mostly) gives 30+ fps almost all of the time. Playing with all settings medium, 1920x1080, gives 100+ fps for 95% of the game, the one time I tried it.

The one advantage of the quad-core is that the ram operates at the fastest commonly available (non-desktop) speed: 1333MHz, but I really don't think that has much of an effect in games.

 

Thanks for your reply
