Buying new pc, these specs yay or nay?

So I'm looking to a custom rig from ibuypower that totals a little under 1k with an

Intel® Core™ i5 750 Processor (4x 2.66GHz/8MB L3 Cache)

Liquid cooling

4 GB [2 GB X2] DDR3-1600 Memory Module

ATI Radeon HD 5670 - 1GB

and windows 7

I'd go out and build one from scratch but I just don't have the time. So those are the muscle of this thing, should I go with it?

Look at this one, just change the 5750 with a 5770.

no mostly there overpriced rubbish omitting the core i7 780, 785k, and 980x

phenom II x3 and if you can squeeze in a sound card then audio editing will always be better with one of those.

Well the comp i got now is almost 5 years old here's a new build i made up http://www.ibuypower.com/Store/Configurators.aspx?mid=397&t=c&c=2090047 I need something that'll last me a few years

Alright I've switch a few things such as

AMD Phenom™ II X4 945 Quad-Core instead of i5

Dark Knight 120mm CPU Cooling Fan

System ATI Radeon HD 5670

Same amount of memory though.

If you're spending a thousand dollars on a computer, you're really not doing yourself any favours by picking one of the weakest DX11 cards on the market right now. That Dark Knight cooler is pointless to get unless you're planning to overclock your processor. Judging by your decision to go pre-built, I'm assuming you're not, so I would suggest spending that money for at least a 4850/5750.
