actually it depends on the model and ur budget, if u hv a creative x-fi sound card i'd recommend for u to go for a creative inspire series (Eg: T9700 is a 7.1) which has decent sounds, around LRK 18k
if u hv more money go for a Gigaworks series ( eg: Creative S750 GigaWorks 7.1 ) which has...
CPU - C2D E8400 3.0GHz
Mobo - Intel DG35EC
mine got several months ago, and of course GTS250 a is decent VGA, danata gahapu hema game ekakma hodata wada kala, btw I hv a 17inch widescreen though; you should run a benchmark via 3DMark Vantage.
no machan, it's XFX... , and it needs a good cooler to over clock , idle temps are around 60-65C, therefore I dint try to over clock it. maybe after installing a good cooler :)
