What model parts do I want for my computer?

<p>I’m working on a STEM degree, and my current computer isn’t running the software I need. I need to get something with better capabilities, and I’ve decided I want to build it. This is because I want to upgrade parts whenever finances permit. I’m starting with around a thousand. I want to build a Windows 8 desktop. I have a monitor, mouse, external speakers, and keyboard. From my current computer, the only part I believe I could use is the DVD drive. I might be able to use the fans, but only if I bought more. The other parts function, but aren’t powerful enough to fit my needs, and the case is, I believe, too small for what the new computer will be. With a thousand dollars, what’s the most powerful combination of parts I could put together?</p>

<p>Basic high performing computer:
Case (reusable as long as it is a standard ATX or some variation). Otherwise a basic $40-$100 case is fine.
Motherboard: $50 min, $80-$100 average, $150-$200 if you want multiple video cards for gaming.
CPU: $50 min, although I suggest the Intel I3 for around $120. I5 up to $180. I7 only if you want to edit video. Stock cooler is fine.
Powersupply: $50-$100 Get quality, 400-500 watts (efficiency of 80 plus or better certified). 750 watts or more than that if you have multiple video cards
Memory: $50-$100 for 8-12GB.
Windows 8: Anywhere from $40-$100, depending upon if you can get a student price.
SSD hard disk for Boot (100GB): $100
Mechanical hard disk for data (500gb-2tb): $50-$100</p>

<p>Video: HD4000 included in the newer I3 & I5 - $0 (make sure the motherboard supports onboard video)
Otherwise, you are looking at $20 for a basic card to $200 or more for gaming cards. $100 will get you a nice one.</p>

<p>Note: AMD CPU’s are cheaper, but I find Intel’s run cooler.</p>
