Need Advice On New Computer

Just trying to upgrade from a laptop that has a battery life of roughly 15 minutes and can't run flash games properly to a computer that run new games reasonably on the (relatively) cheap. Just making sure I'm not making stupid mistakes about my computer.

This is basically the end of my budget because I have to buy a monitor/speakers/mouse/keyboard, but I might be able to scrounge up 100 dollars or so. I really have no problem upgrading and I'll do so when I start to feel held back by my computer. I might try to get into light overclocking (just the safe stuff), but if I do I will be investing in additional sinks/fans.

Thanks for any help you guys can give.

It probably wont run that well without a motherboard

DVD drive - my first choice is Samsung, second choice is LG.

...Right.

This was the monitor I was going to get

The HD3870 for 60 dollars seems like way to good of a deal to pass up so I'll be grabbing one of those and the Antec Sonata looks fine for a case.

Since it was recommended and cheaper I'll most likely go with the E5200.

Thanks for the help.

No real reason that I put together a list without a motherboard and a hard drive, besides wanting to get some feedback quickly and not actually rereading my post. I've got a copy of 64 bit Vista ready and waiting and I've got the monitor picked out. This is the hard drive I'm looking at.

(70 dollars)

Come to think of it, I know virtually nothing about picking out a hard drive. Basically all I did was hit top sellers and 400-700gb.

Last question before I buy...
Looking at how cheap the HD4870's are right now I was wondering if I should be looking into that as an option. I question how much I actually need more then one video card and if the jump in price would be worth it. I guess I would need a nicer motherboard and power supply, but I'm worried that if I go to cheap I'll wind up regretting it later. Should I think about crossfire? If I did how much more would it cost me?

Shoot, that was two questions.

4870s are a pretty good buy right now, and if you have a crossfire board getting one 4870 is not a bad choice. I just picked one up.

If you know you will not crossfire ever, then the GTX 260 (core 216 variety) IS the better buy.

However, unless you are going to upgrade your processor as well, 4870 would seem a bit mismatched with an E7200.

Likewise if you are going to crossfire two 4850s, you need more CPU power.
