no its not worth to pcik up 1600 mhz ram for etra 25 if u play games. HAF CM series are really good, so consider them cauz they perform jsut as good as 1200 but cost less. Get a corsair PSU. Otherwise pretty good ^^
is there any reason as to why i should get a corsair PSU? i was thinking of going for the cooler master case when i was making this build but i think that im going to stick with the antec case because it looks nicer and has better airflow
+1 on the Dark Knight, Scythe Mugen 2 is also a awesome heatsink for the money. I do not know a whole lot about PSUs but I went with alot of the recommendations I got here about corsair and so far it runs quiet and smooth.
Considering your future plans, I'd opt for a better PSU. I put the Antec Signature 850 in my 1200 cases. The Corsair HX series is an equivalent which I'd use in an HAF 932 if the client wanted a more aggressive case style, but w/ the Antec case, I think the Signature is the better choice. The Corsair TX and Antec TP series are next level down.
The 640 GB Black's are not among the top performers though the 2 TB model is. Check the performance charts here making sure to consider temperature and sound:
For Photo Editing or CAD work (if that includes rendering) you will want to avoid a TN LCD panel. Best choices, though they will put a damper on your budget, are the Dell 2408 S-PVA panel and it's successor the U2410 H-IPS panel. Both will give you 1920 x 1200 as oppossed to 1920 x 1080. I like the extra real estate at the bottom of screen as playing at 1920 x 1080 leaves me access to task bar and other goodies. The 2408 WFP runs about $440, the 2410 can be had for $480
