NOW THOSE specs look a little more down to earth. The GTX 295 is a GREAT card, but a GTX 285 will run pretty much anything you want to. The only think that stands out is the Hiper 880w power supply. I am not familar with Hiper so I can't really say anything. 880w is alot for a single card, and to tell you the truth I don't see you going quad SLI anyways on a 24" lcd. The only reason you would need it is if you were actually gaming on more than 1 monitor, or on a 30". And to be honest the only multi display setups that I'd look at are 3 LCD's running Tri SLI, one for each monitor. But there is ALOT of money involved in that type of setup. 24" with a single powerful card is the way to go. What I've done in the past is just sell off my current card after a year+ and use that money for the latest and greatest.
And just to comment, your buddy is an @ss. "My friend's PC has the highest specs. I think the highest it can be. And what he is saying is that people from forums only tell you to get 920 because they can't afford 965." I'd like to know what HIS specs are. I promise you they aren't the highest they can be, there is always someone out there with more. Plus his comment about "people from forums", only shows he doesn't below to a forum and only believes what goes on in his own little mind. Therefore, he is ALWAYS right, to himself. I would take anything he says with a grain of salt, because when it comes to technology, no one has all the answers, they is why there are tons of forums to share knowledge. I have a feeling he is wrong... ALOT. At least here you have dozens of people contributing and sharing in a friendly manor. You will get several answers to everything, but we usually agree on alot in the end once we discuss. And about his comment on we can't afford a 965... Yes, I can afford it and if I wanted it I would have bought it. But why would I waste my money on it? I can OC my 920 to 4GHz for 1/4 the cost. He sounds like a stuck up snot. Sorry for choppin away at your friend, but he sounds very stubborn and close minded.
Also, could you let us know what you intend to use your PC for. If you have a 6 year old PC, you aren't playing modern games, so are you intending to start? I don't want to sound like a punk, but are you just trying to 1 up your friend or impress him? If so... Don't. Unless you are getting good use out of your system, there is no scenes in going over the top. I really like the build you put together above, but maybe cut back on your video a little. the GTX295 is highend, under it would be the GTX285, then the GTX275 = HD4890. I'd stick with something in there because they are ALL highend cards. But if you are budget limited the 4870 is probably your best Value and still highend, the GTX260 is to. Both of which will play any modern game on high on a 24".
