APPROXIMATE PURCHASE DATE: Tomorrow (GMT+8)

BUDGET RANGE: 1200 - 1400 SGD, lower is better.

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming (Battlefield 2142, Dynasty Warriors 6, SC II when it comes out), word processing, watching DVDs and stuff, nothing too demanding.

PARTS NOT REQUIRED: Mouse, keyboard, monitor, OS (Win Vista Ultimate 32 bit)

PREFERRED WEBSITE(S) FOR PARTS: http://www.fuwell.com.sg , http://bellsystems.com.sg/index.aspx?uc=products_pricin...

PARTS PREFERENCES: None, there's a very limited selection of product/brands here in Singapore.

OVERCLOCKING: Maybe

SLI OR CROSSFIRE: Yes, when I save up enough to get another GPU

MONITOR RESOLUTION: 22" 1680x1050

ADDITIONAL COMMENTS: Been using a crappy HP pavillion laptop from 2006, definitely need a new computer instead of using the workstation in my lab to play games.

Here's the list of parts I'm thinking about getting:

MoBo + CPU: MSI 790GX-G65 + Phenom II X3 720 414 SGD
PSU : Corsair HX750 modular PSU 249 SGD
GPU : Sapphire HD5850 1GB 399 SGD
RAM : Kingston PC3-10600/DDR3-1333 2GB RAM 65 SGD
HDD : Western Digital 320GB 67 SGD
Case : Cooler Master Elite 330 69 SGD
Optical : Samsung S223 22X DVD+-RW 32 SGD
WLAN : Linksys Wireless 54G PCI adapter 38 SGD
Webcam : Logictech C120 25 SGD
__

Total: 1358 SGD

I do realize that the 5850 will probably be an overkill, but the 5770 does not perform nearly as well as 4870 (although I don't think it'd be noticeable at 1680x1050), so I'm still debating on which one to get. I am wondering, though, if the 5850 will be able to fit inside the small Elite 330 case. I'm also thinking about replacing the HDD with 500GB Caviar Black, which should run a lot faster, and doesn't cost that much more.

Cooler Master Elite 330 and HD 5850 is not a problem. It will fit easily.
-> A slight overclock on the 5770 and its very close, maybe even a bit better than the 4870.
WD Caviar Black or Samsung F3 500GB are both a performance upgrade over WD 320GB. Samsung F3 if the prices are close.
Corsair HX750 is oversized (and overpriced) for 2x 5850 video cards. 600-650W will be plenty of power if you choose a good PSU. Can you get an Antec Truepower New 650W? It's partly modular, plenty of power and a very good PSU.

Agree with WR2 on power supply. However, there is only a limited number of 650W power supplies out there with 4 x 6-pin connectors. Antec TP-650 is one, but it is very expensively priced in Asia.

Will an CM Real Power-Pro 650W work? Antec TruePower is available at another store, though I was hoping to buy all the components from the same shop for better bargaining leverage (which I've heard is doable here... I've never tried bargaining for computer hardware, though...) and easier RMA process.

I did some calculation before using the PSU calculator on Corsair's website, and apparently two 4870 crossfired with a slightly overclocked system seems to need around 700W of power.

Samsung F3 is not available here, so I guess I'll have to go with WD Caviar Black.

Thanks for the feedback. =)

Edit: Just read the CM website, apparently RP-Pro 650W only has two 6pin PCI-E connectors =/

Yeah, so I checked the price lists, and it seems like I'll either get the Antec TP650 from the other shop or Corsair HX750 from the current shop (the only other PSU from a well-known brand with 4 6pin pci-e connectors is CM UCP 700W.)

I will go ahead a do another PSU calculation to make sure that 650W is enough for 5850 Crossfire. Thanks guys.

Sapphire website recommends a 600W PSU for 5850 crossfire. Check the requirements at the bottom of the page. And that would be an 'average bargain PSU'.
So a quality 650W PSU like you've listed would be a generous amount of extra power.

Even if you can't find a PSU in the 600-650 range with 4x PCI-e connectors you'd be able to use the molex-PCI-e adapters that come in the video card accessory pack to get enough power for the cards.
Might not look 'pretty' but will get the job done.

Adapter under the EAH title on the box in this picture - not all cards have that adapter in the accessory pack but you can buy them separately.

Oh, good, thanks. I guess I have everything setup for tomorrow than.

Thanks a bunch, guys =)
