I could use a little help with my system upgrade. I've recently come into some "extra" money (if there is such a thing, yay tax returns lol).

Mostly looking for possible compatibility issues or anything i may have overlooked.

I am set on the Amd choice, so please no attempts to dissuade me from that.

Let's start with my Current system (built by a friend):

Case: Logisys Case-51W
PSU: OCZ GameXStream OCZ700GXSSLI 700W ATX12V SLI Certified CrossFire Ready Active PFC Power Supply
HDD: Western Digital Raptor X WD1500AHFD 150GB 10000 RPM 16MB Cache SATA 1.5Gb/s Hard Drive
Chip: Amd athlon x64 x2 4400+ 2.25Ghz
MoBo: ASUS A8N-SLI Deluxe 939 NVIDIA nForce4 SLI ATX AMD Motherboard
GPU(s): 2x SAPPHIRE 100259-1GL Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card
Ram: 3 gigs of wtfever (read: not that great and ready to replace not to mention 32-bit xp only makes 2.75 available)
OS: Win XP home SP3 32-bit


I'd like to work on a new build reusing some of my components (Case, PSU, HDD), while upgrading my gaming performance as well as some light web dev (mostly dabbling) and other misc stuff.

Here's what I'm looking at for my updated rig:

Case: Logisys Case-51W
PSU: OCZ GameXStream OCZ700GXSSLI 700W ATX12V SLI Certified CrossFire Ready Active PFC Power Supply
HDD: Western Digital Raptor X WD1500AHFD 150GB 10000 RPM 16MB Cache SATA 1.5Gb/s Hard Drive
Chip: AMD Phenom II X4 940 Deneb 3.0GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM2+ 125W Quad-Core Black Edition Processor
MoBo: ASUS M4A79T Deluxe AM3 DDR3 AMD 790FX ATX AMD Motherboard
GPU(s): 2x SAPPHIRE 100259-1GL Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card
Ram: looking at DDR3 1600 modules, no standouts, kinda pricey, but i realize with this mobo I'll be using 2 channel kits
OS: Win 7 beta 64-bit

So I suppose my questions are these:

1. Are these all compatible pieces?
2. Is it worth the cost for the DDR3 1600 ram?
3. For the price range is this looking like a decent rig?
4. Any suggestions/foreseeable problems (aside from Intel suggestions)
5. Cooling solutions? Considering water (Koolance Exos?)?, but any suggestions for a good CPU cooler would be nice.

(Edit: added cooling question)

if you can afford it, go with DDR3. but why go with that cpu? your motherboard even supports the new AM3 phenom II's, so why not get one of those? they're faster and they cost less.

EDIT: actually i think you don't have a choice on the cpu issue. The AM2+ cpu's don't even have a DDR3 memory controller. either get an AM3 cpu or change the motherboard.

Well I was actually debating this internally. I suppose my only real reason was to go with the tried and true performer, but I didn't realize the AM2+ wouldn't support the DDR3 as you've mentioned.

My initial choice was:
AMD Phenom II X3 720 2.8GHz 3 x 512KB L2 Cache 6MB L3 Cache Socket AM3 95W Triple-Core Black Processor - Retail

Not sure why i convinced myself this would be a bad chip (or the deneb a better one), but if it supports DDR3 this is likely what I'd go with. Any issues with this chip?

(edit: Typo)
