Default Upgrading PC

Hi so I have a nice check coming in this week and I'm going to use some of it to upgrade a part on my PC, built it last about Thanksgiving 2010, but I'm not sure which part to upgrade. Heres what I have now....

Case- Rosewill Smart One ATX Mid Tower Computer Case

PSU- Newegg.com - Rosewill Xtreme Series RX950-D-B 950W Continuous @40°C ,80 PLUS Certified, ATX12V v2.2 & EPS12V v2.91, SLI Ready CrossFire Ready, Active PFC "Compatible with Core i7, i5" Power Supply

Mobo- Newegg.com - ASUS Crosshair IV Formula AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard

HDD-http://www.newegg.com/Product/Product.aspx?Item=N82E16822148433

CPU- Newegg.com - AMD Phenom II X4 955 Black Edition Deneb 3.2GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor HDZ955FBGMBOX

GPU- Newegg.com - SAPPHIRE 100314SR Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity

RAM- Newegg.com - CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model TW3X4G1600C9D G

CD Drive- Newegg.com - ASUS 24X DVD Burner - Bulk 24X DVD+R 8X DVD+RW 12X DVD+R DL 24X DVD-R 6X DVD-RW 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM Black SATA Model DRW-24B1ST/BLK/B/AS - CD / DVD Burners


Computer is used for all gaming. Can run Wow on just about maxed settings, Crysis 2 on maxed settings with dx11 update, battlefield, Black Ops, Need for Speed...
So just wondering what the best "worst" part is that I should look into upgrading. I'm kinda thinking the RAM, about used when playing some games is getting close to around 80% and I'd like that to be lower...but if I want to upgrade RAM should I buy whole new RAM set with 8GB or can I get one just like it?
Thanks for your time, looking foreward to feedback!

About all I would touch is maybe a 6core and I would replace that psu with a quality unit from Corsair or Antec.

whats your budget for upgrades?
you can either buy a 8gb set, or add another 4gb set. completely up to you.
I'd suggest buying a 8gb though, since ram is like... CHEAP now days.

I'd honestly, for the sake of your systems health, get a more quality power supply. You only need a 600W psu tops, even a quality 500 will be more than needed.

A Corsair 750tx has almost the same amps as the rosewill 950, and cleaner power output.

From the AMD website for the 6870:
Quote:
500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for AMD CrossFireX™ technology in dual mode)
Its not that Rosewill is exactly "bad", its just that there are brand options that are more reliable and efficient.
TF PSU Thread

$89.99 w/MiR Corsair HX650 (modular).
$69.99 w/MiR PC Power and Cooling 650w.

Or the 750w versions for more headroom
$129.99 w/MiR Corsair HX750 (modular).
$89.99 w/MiR PC Power and Cooling 750w.

The bad parts are the lower quality capacitors, it does hold the power cleanly, and while it says 950W, it'll perform more like a 850W psu. Also notice the ratings are at 25C... my house isn't even that low..

On the 650 side of psu's, watchout as most wonm't have enough pci-e cables.

Also look at Antec psu's. Great psu's with good Amperage.
Newegg.com - Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "compatible with Core i7/Core i5" Power Supply
This Antec is only 750W yet it has 4 25A rails, where as the Rosewill nis 950W and 4 20A rails.

So I'm liking the look of the modular one from corsair. Newegg.com - CORSAIR Professional Series HX750 (CMPSU-750HX) 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active PFC Power Supply
This might be a stupid question but better safe then sorry....
This one says that it has, PCI-Express Connector 4 x 8-Pin but my GPU needs 2 x 6-Pin(4 once crossfire) can I still use a 6-Pin in a 8-Pin? Or is this PSU not going to work?
Thanks again!

Yeah that threw me off the first time I saw it too.
For some reason they list it as an 8-Pin instead of a 6+2-Pin, which is what it really is.
To totally ease your concerns check out Corsair's HX750 spec page, pictures, quantity, and length of cables are under the FAQs & Support tab.

Ok sweet! Thanks very much!

One last quick question before I think I'm all set, I'm going to try and sell the current PSU I have, how much around do you think I should ask for it? Bought it for 120$ here's the link again...
