Hello,

So I've been researching this for roughly 3 weeks on various boards and I've come up with a general parts list for my potential new gaming computer:

AMD Phenom II X3 720 2.8GHz Socket AM3 95W Triple-Core Black Processor Model HDZ720WFGIBOX
+
GIGABYTE GA-MA790XT-UD4P AM3 DDR3 AMD 790X ATX AMD Motherboard
http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...

G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model F3-10666CL8D-4GBHK
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

SAPPHIRE 100259-1GL Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

PC Power & Cooling S61EPS 610W Continuous @ 40°C EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply

COOLER MASTER RC-690

Western Digital Caviar Black WD6401AALS 640GB 7200 RPM

XIGMATEK HDT-S1283 120mm Rifle CPU Cooler

LG 22X DVD±R DVD Burner Black SATA Model
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Approximate purchase date: Within the next month

Budget Range: $800-900 USD. Maybe $950

System Usage: Gaming and watching movies

Parts not required: Monitor, keyboard, mouse.

Overclocking: Yes

Monitor resolution: 1920 x 1080 (Acer H233H 23" Monitor)

Overall it puts me at $828.90 before rebates. I'm pretty sure on my processor, hd, case, and burner choices. I'm not entirely set on my mobo, gpu, ram, psu, and cooler choices yet however. I do plan to do some overclocking (cpu, gpu) but at this moment in time, I do not think I'm going to want to crossifre. In the mean time, will these parts be compatible with eachother and are there any more optimal solutions?

Thanks

All good choices, except for the PSU. The PSU you chose is very high quality, but its kinda in an awkward spot for your system. A decent 500w PSU would be good for your system, like the PC P&C 500w Silencer, or maybe check out the OCZ StealthXstream 600w PSU (about the same quality as the 500w PCP&C) or maybe a Corsair 550vx. If you want to xfire later with another 4870 down the road, then you should be looking at a 700-750w PSU. PC P&C silencer 750w, or a Corsair 750tx would be the best options there.

If you have $900 to spend, why dontcha get i7+HD4850 or even hd4870? Really should be within reach if you stick to only 3gb ram and value case/psu

For $900 he would have to get very basic i7 parts, it would require cutting too many corners IMO to make it worth it. Upgradability would be reduced.

that might be in the budget but it would not be as good a gamer as the OP's first choice and I dont think he wants to buy a computer he has to upgrade beofre its any good for him .


I like the original power supply , but I'd spend the rest of the budget upgrading to a 4890 gfx card . That way theres be no need to consider xfire in the near future

Thanks for all the input guys!

So upon further consideration, I think I will scratch the HD 4870 and go with the XFX Radeon HD 4890. This one seems to be the highest rated on Newegg.

Thanks for the PSU suggestions as well! I'm stuck now on deciding whether to get the OCZ Fatal1ty 550 or the Corsair 550vx now. It seems the big difference between the two are that the OCZ has 2 +12V rails and is modular, whereas the Corsair is not modular and only has 1 +12V rail. Can anyone tell me how that difference affects my build?

A single 12V rail can be better in some circumstances . Imagine you have 2 x 25 watt rails and 3 x 15 amp devices which wont run

versus 1 x 50 amp rail which will run 3 x 15 amp devices .


I would go back to your original psu for a 4890 rig . It gives you some overhead , and because its not running even close to its max power then it will be cooler and quieter
600 - 650 watt would be plenty

Also great is the corsair 650 tx for $75

PS . the 4890 was released DAYS ago so the reviews are very short term . All the 4890's will probably be identical reference designs made by ATI and rebadged by XFX , Sapphire etc . Buy the cheapest one , or the one with the best game bundle IMO

+1 for the Corsair 650TX

Though the psu you originally chose is excellent as well.
April 17, 2009 7:11:32 AM

Alright I'm pretty sold on the 650TX. I actually initially chose that for my build but for whatever reason I switched it with a PC P&C later, I forgot why.

The only thing I'm still deciding on right now is which HD 4890 card I'm going to get.

Thanks again for the help!

Ah sweet. Guess I'll just go with that then.

Thanks a lot everybody!

Everything looks good. That PSU should be enough, but if a comparable Corsair, FSP, or Antec was on sale don't pass that up. You could save a few bucks by going with the DDR2 model of that board and DDR2 RAM, but considering your current choices aren't too much more I'd say it's worth it to go with the DDR3 setup. While phenom IIs will continue to support DDR2, the next generation will be DDR3 only and thus not work in DDR2 boards.
