Ok, this will be my first build and I'm nervous, and would like you guys to take a look at it.

Case: Aspire X-Plorer- $58

Motherboard: EpOX Nforce4 Ultra- $85

-or-

Asus A8N5X Nforce4- $86 (or if you guys don't recommend either of these, then what do you suggest for this price range?)

Processor: AMD Athlon 64 X2 3800- $297

Video Card: eVGA Geforce 7800GT- $285
http://www.newegg.com/Product/Product.asp?Item=N82E16814130256

PSU: Thermaltake 500W ATX 12V 2.0- $79
http://www.newegg.com/product/product.asp?item=N82E16817153028 (Now about this, it is a 20+4 pin power supply, but those mobos are 24 pin. Are they compatible? I read the sticky, but couldn't make sense of it.)

HDD: Seagate Barracuda 80GB SATA 3.0GB/s- $58
http://www.newegg.com/product/product.asp?item=N82E16822148107

DVD Drive: Lite-On IDE DVD Burner- $38
http://www.newegg.com/product/product.asp?item=N82E16827106014

Windows XP w/SP 2- $93

A couple of questions about this. Do I need a floppy drive? Someone said that I need one to install SATA drivers. Also, are there any compatability issues between any of the items? Thanks for any help.

Edit: I already have 1GB of RAM

Not bad, get rid of the TT PSU, the 450W fortron is a much better buy @ $50. You don't need more than the 400W one but for another $10 why not?

You don't need a floppy drive, but once a year or so it comes in handy.

Otherwise not bad at all.

E2A: I'd go with the asus A8N E or the epox, i think the epox is the better OC board though. Oh and you are buying some RAM aren't you, and it is 2gb of the cheapest stuff you can find?

im in the same boat as you buying a new system, and looking at these epox boards.

i dont know anything about em, so i cant tell you if they are good or not...but this one i gave a link to is sli for like 20$ more.... nice to have the option atleast..for 20$ why not?

im getting 6800gs and when the price drops..to like 100$ or something i can pop in the second one.
