Concerning the $1000 PC, I think that it is a bit of overkill with HD7970 there. In that price category, to get the most of an "enthusiast PC" (see my earlier post above concerning the $2000 PC), I would have gone for an easily overclockable AMD FX system with 4 modules. Also, from Newegg (All prices with rebates):

TOTAL: $1,062.91
Ok, a few dollars more than the $1000 PC in the article, BUT ok then just switch to the same chassis case and there you have it!
So why is this better in my opinion?
1. SSD (do I have to say more on this one?) + Mechanical drive
2. Double the RAM. Yes you will appreciate it if you create RAM-disk or do Photoshop/video editing, compressing/uncompressing files for instance.
3. Bulldozer CPU, sure not the highest IPC or efficiency, BUT at least there is some fun ovecklocking it and getting more value out of it. Ok, a better heatsink may be needed for those higher voltages but that can always be arranged later. One should be able to raise the mult quite a bit on this one without upping the vcore.
4. Better PSU. TX series from corsair with 50W more of future-proofing
5. Antec nine hundred seems like a more solid case in my eyes.
6. Total cost is basically the same.
Downsides:
1. GPU performance in games, one step down from 7970
2. Single-threaded CPU performance significantly lower than the i5
What do you guys/gals think?
