New PC - Dual GPU Cooling question:


Recommended Posts

Hey guys, I will be building my new i7/4890 build soon and I want it set up so it can take 2 of the 4890's, as I will be purchasing a second in a few months. Atm this is my ideal build:

 

WWW.PCCASEGEAR.COM

 

Memory: OCZ DDR3 PC3-10666 Platinum 3x2GB - $159.00

GPU: Sapphire Radeon HD4890 Overclocked - $315

PSU: Corsair TX-750 750W Power Supply - $219 OR

Corsair TX-650 650W Power Supply - $169

CPU Heatsink: CoolerMaster V8 CPU Cooler - $89 OR

Xigmatek HDT-S1283 CPU Cooler - $55

Optical Drive: LG GH22NS30 SATA DVDRW Black OEM - $55

 

Total: $831 or $753 with cheaper option heatsink and PSU.

 

MSY

 

CPU: Intel Core i7 920 1366pin-series - $392

Mobo: Gigabyte EX58-UD4P - $329

HDD: Seagate SATA 500G - $74

Case: CoolerMaster HAF 932 Case - $209

 

Total: $1004

 

Complete Total: $1840 or $1757 with cheaper PSU and heatsink.

 

I'm thinking maybe I might need to get a larger wattage for the power supply to support crossfire 4980's? I'm not too sure. Any suggestions would be great! Thanks guys. Please note also that I will be planning on doing a little bit of overclocking, pushing the i7 to about 3.2 and the GPU a little also. So the cooling and power supply must also be able to take this

750W should be more than enough for 2 4890's (correct me if I'm wrong).

The rest of the build looks great :) Just make sure you call MSY and ask about stock before making the trip and waiting in the never ending line. Also why not get the Optical Drive from MSY? Their Sony and Samsung at 35 dollars SATA DVDRW. (Just a thought, might save you 20 dollars)

And to any people thinking these prices may be a little crazy. He, like me is Australian :) So all prices AUD.

 

Enjoy building it :)

Msy sells XFX 4890 1gb for the same price. It has a lifetime warranty which is probally the best pick. I doubt Msy will pick up there phone. My brother had to get his Mobo rmaed and they didnt pick up for 3 days straight.

Thanks to the both of you for the replies. You think the XFX is a better option, even though the sapphire is overclocked and the same price? I guess I could overclock the XFX myself, any advantages to the XFX other that warranty? :) Also swapped the Optical, thank for the suggestion! Saves me $20 :P

Depending on the MSY store, you should be able to email ahead and have your order ready to be picked up in "Quick Chop Chop express order line"...Ok so maybe i had my boss at my night job (Chinese food delivery boy) saying "Chop Chop. you go now!!" to me all weekend...

 

Not sure if they are actually using the "Quick Chop Chop express order line" or not but they advertise it (I Think...)
