looking to buy or build a new computer

[Anonymous]

I am generally working with laser scanned 3d models, so very high detail.

My current computer is a Inspirion 546 with an amd phenom quad core 2.3 ghz, 8 gb of ram, and a ati radeon hd 4300/4500

one thing that I was informed was that the powersupply really sucks.

not sure if I should attempt to build one, whileI havent done such a thing in a while but feel I should get my feet wet again 

Or just bite the bullet and get a new dell. however I really dont want to spend a huge amount of money I was thining at max around 900 something but def under 1k

I was almsot tempted to just get a new dell though I am worried about windows 8:

Windows 8, 64-bit, English
12GB Dual Channel DDR3 1600MHz - 4 DIMMs
16X CD/DVD burner (DVD+/-RW), write to CD/DVD
AMD Radeon™ HD 7570 1GB GDDR5
Black w/19:1 Media Card Reader
3rd Generation Intel® Core™ i7-3770 processor (up to 3.90 GHz)
2TB 7200 RPM SATA Hard Drive 6.0 Gb/s
Dell Wireless 1703 802.11b/g/n, Bluetooth v4.0+LE
Integrated 7.1 with WAVE MAXXAudio 4
Integrated 10/100/1000 Ethernet

on build I found only had these stats

Intel Core i7 3770k	$340
Gigabyte Z77X-D3H	$142
16GB Corsair Vengeance DDR3 1600MHz Memory	$95

Corsair CX430 Power Supply	$38
Cooler Master Hyper 212 Plus	$25
Windows 7 Home Premium 64-bit	$89
Pricing via Amazon, so no tax or shipping for most USA Residents	$994

Any advice you can give would be great right now my comp chugs sometimes, sadly I dont know how to check a polygon count but a faces count I found on the scan I am working on now has 7.5 million faces. So I need something to take the edge off.

What Autodesk software will you be using?
Are you aware of currently unsupported-in-Win8 software from Autodesk: http://autode.sk/TGvR3t
