Which games i can run on my pc, please mention names...?

i dont think the latest games will run smoothly .. you can run games like dirt 2 or nfs undercover but that also at lowest settings and i would suggest you to use a software called GameBooster ( google it ) .. and do install a seperate graphics card like ati 5770 or better if you want to run latest games ... then the games will run smoothly even at highest or close to highest settings ..
