you could save some by dropping to 6gb kit (3x2BG) if gaming; the extra 12 GB has no benefit except to separate you from your dollars. If gaming at 1920x1200 is a priority, dump any saved money into a GTX580 if possible.
I'll be gaming and using other programs like Sketchup, photoshop, and what not. Gaming wise, I'm only playing Guild wars 2, maybe starcraft 2 on this machine. No FPS or anything else. So, that expensive card won't be necessary for me lol.
Other than that, 6 gigs could cover it. I want this machine to last me for about 4-5 years. Everything else checks out though? All those components will work together??
Yeah, you'll only need 6GB RAM (you can add more later since there are 6 RAM slots).
I would bump up the PSU to the 750HX (not TX). The quality is a bit better, and you'll get more power and modular (i.e. removable) cables.
Also, ditch that Caviar Green hard drive. It's going to be as slow as molasses doing anything, since it's at laptop-drive speeds.
I would also recommend a good, cheap CPU cooler like the Coolermaster Hyper 212+ if you're going to be doing a decent amount of work on your system. It's under $30 on Amazon with free shipping, and it's cool and quiet.
Alright. Why don't I bump it down to 650HX (modular)? I'm thinking I won't need the 750. We're talking about that graphics card, the CPU, the case fans, motherboard, maybe 2 HDD's eventually needing power. 650 watts cut it for all that? Alright, I'll get rid of the slow HDD then .
The stock cooler won't cut it for the CPU? The case itself has SO many fans already.
Sorry, didn't get a chance to get online since then.
You should be fine with the 650HX. I was just trying to get you to get a HX model, since it is built better and is modular. My 650 delivers about the same power, and look at what it runs
Those Caviar Greens are meant for things like enterprise data storage; they access information so slowly that it would make your life miserable because Photoshop and the like would take minutes to load.
The stock cooler will work ok; I was just saying that if you plan on doing a lot of work on your computer often, a good cooler would be a good idea. Plus, it ain't all that expensive I did a stress test in my system and never hit over 50C
EDIT and since your non really gaming, you could just drop the 6870 in my build and change it out for a 6850 or your 5770. That'll drop it down to your price. You'll see better performance with the newer architecture.
