during the huge dell sale, i bought a dell 5160 while my gf bought a 600m. i figured w/ a 3.2 gig processor and 512mb of ram, that it would be able to handle games such as WoW decently. it turns out that the 600m outperforms by a good margin. is there any way i can upgrade my computer to handle games better? or should i just sell my laptop pick up a 8600 in the future? if i was to upgrade the video card myself (if possible), how hard is it to do and how much would it cost? i've built my own computers before, but have no experience w/ laptops. or maybe my video card isn't the main issue? perhaps my 60 gig ultra ATA hd or 512mb of ram is the bottleneck? help would be appreciated, thanks
