New Gaming Rig for around $550

APPROXIMATE PURCHASE DATE: Within a month BUDGET RANGE: $500 -$600

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming & Movies

PARTS NOT REQUIRED: Case, Hard drive, keyboard, mouse

PREFERRED WEBSITE(S) FOR PARTS: newegg

PARTS PREFERENCES: AMD Phenom II, ATI Video card

OVERCLOCKING: Most Likely, tho not hardcore. SLI OR CROSSFIRE: Crossfire

ADDITIONAL COMMENTS: This is going to be a new gaming rig, while I harvest some parts from my current machine. It will also run Windows 7 64-bit. Down the road, I will want to do Crossfire and Blu-ray. So right now, it's a pretty modest build, but I want to be able to add an additional video card to enable crossfire and be able to play Blu-ray media.


Here is what I have already priced from Newegg:

ASUS M4A78T-E AM3 AMD 790GX HDMI ATX AMD Motherboard

AMD Phenom II X3 720 2.8GHz Socket AM3 95W Triple-Core Black Processor Model HDZ720WFGIBOX
http://www.newegg.com/Product/Prod [...] 6819103649

SAPPHIRE 100277L Radeon HD 4770 512MB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card

RAIDMAX HYBRID 2 RX-630SS 630W ATX12V V2.2/ EPS12V SLI Ready CrossFire Ready Modular Modular LED Power Supply
http://www.newegg.com/Product/Prod [...] 6817152035

G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Dual Channel Kit Desktop Memory Model F3-10600CL9D-4GBPK

LG Black 22X DVD Burner
http://www.newegg.com/Product/Prod [...] 6827136152


The total cost from Newegg on those is around $565 with shipping. Not too bad considering the expandability.

Change the PSU again, this time to Corsair 650TX. It's the same $80 as that Purepower 600W but twice as powerful (52A vs 29A). Thermaltake should be ashamed of themselves, calling that junk a 600W PSU. It should be labeled 400W. It's not at all appropriate for HD 4770 Crossfire.



If you can afford $44 more, replace the MB/CPU/RAM with these:

AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W $325 combo
GIGABYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD
http://www.newegg.com/Product/Comb [...] mbo.190735

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 $59
http://www.newegg.com/Product/Prod [...] 6820231166

No problem.

How about this combo then?

X3 720 + GA-MA790X-UD4P
http://www.newegg.com/Product/Comb [...] mbo.190734

It's for DDR2 again, but really that doesn't make any difference in speed. It would save you $60.

The X3 720 + GA-MA790X-UD4P works for me. I really wasnt sure about DDR3, but I was liking the idea of having it anyway I switched the ram to Kingston HyperX DDR2 1066 http://www.newegg.com/Product/Prod [...] 6820104073

That has brought the total system price down to ~$515 shipped.

TBH I don't like that Kingston RAM. Have you noticed it says 2.3V in the specs? That's a bit much IMO. The G.Skill I linked earlier has the same 5-5-5-15 timings at 2.0 or 2.1V instead, so it's better.

Also, if you check the memory support list at
http://www.gigabyte.com.tw/FileLis [...] x-ud4p.pdf
The G.Skill model F2-8500CL5D-4GBPK is there. The Kingston model KHX8500D2K2/4G isn't. It may work all right, but Gigabyte has not tested it and makes no guarantees.

Edit: shortstuff, you type too fast

Neat, HD 4850 for 88 bucks. Nice find!

It supports Crossfire, no worries. You can see some newegg reviewers using it with HD 4870 CF or HD 4850 CF or HD 4770 CF.

It doesn't do SLI. Only x58 boards do both CF and SLI, and not even all of those.

I'm not worried about SLI, cause im an ATI guy myself. I will probably just start with one 4770, then down the road get another one to do Crossfire.

I think you'll be pleased with that. It's going to feel pretty much the same as my own $3000 build from mid-2007 (with Q6600 and 8800GTX).

Be careful about electrostatic discharges, of course. Good luck with the build!

Hey, quick question for you guys since I cant seem to figure out. I know some newer mobo's have an internal crossfire bridge, but I can't seem to find out if the Gigabyte GA-MA790X-UD4P does or not. My video card doesn't come with one I dont think. If I have to buy a bridge, does it have to be made by HIS or Gigabyte?

I looked at the manual for the HIS 4770. I looked at the section about enabling crossfire and it doesnt mention a thing about installing a bridge. I am wondering if not all cards require the bridge to work?

I also looked at the motherboard manual, and it said:
"Depending on your graphics cards, install the connecting bridges on the two cards. (Note: Procedure for enabling CrossFireX may slightly differ by graphics cards. Refer to the manual that came with your graphics cards for more information about enabling CrossFireX.)"

All that leads me to believe that I dont need a bridge/bridges. I guess we will just have to wait and see when I get the other card.

EDIT: This was on the HIS 4770 page:

ATI CrossFireXTM multi-GPU technology takes your gaming experience to the next level with superb scalability, performance and compatibility. The technology combines the awe-inspiring capabilities of multiple ATI RadeonTM graphics cards and an ATI CrossFireX ready motherboard to meet the hard-core demands of your alternate reality. New ATI RadeonTM HD graphics cards are designed with an internal ATI CrossFireTM Bridge Interconnect system to simplify installation.

Gotta love marketing people... So many words, so little useful info in that paragraph.

I think they mean there's no need for those Crossfire dongles that plagued ATI cards in the past - until a few years ago, that is.

Cool. Good to know. Thanks!
