Hi guys,

I am looking for a new computer for school and am having difficulty in narrowing down any good ones.
(I have trouble with computer terms so bear with me)

-What I mainly look for is lots of memory like the 512MB or 4-6GB/Ghz or whatever it's labeled.

-Also the Vista Home Premium 64-bit. I'm not sure if that's the right one so suggestions would be nice

A good graphics card for games and other such things when I'm bored... The Nvidia and Gforce always pop up but I have no idea how to tell which is better

A cd/dvd rewrite or just some kinda dvd player thingy besides the cd-rom drive

I know I've left other stuff out but those are the main things I am currently looking for... or close to it.

Here are some I already found. I prefer HP since that's the only comp I've had for the past....almost 6-8 years... or so. So these are just some ideas. Any help and clearification on the terms or cards, or durability would be a great help

HP - Pavilion Desktop with AMD Phenom™ X4 Quad-Core Processor
HP Pavilion A6750F Desktop PC (2.3 GHz AMD Phenom X4 9650 Quad-Core Processor, 8 GB RAM, 750 GB Hard Drive, DVD Drive, Vista Premium)
HP - Pavilion Desktop with AMD Phenom™ X4 9550 Quad-Core Processor
Systemax Ascent KMA4000 Desktop Computer - AMD Athlon 64 X2 4200+ / genuine Windows® Vista Home Premium / 3GB DDR2 / 320GB HDD / DVD-RW

I'm still looking around, so any help or advice about what I should look-out for will be greatly appreciated

Thanks again for any help,
Decker
