PLS take a look at my new mining\gaming rig i want to buy...

[EnGineer]

Hello,

I'm new to building computers - DIY and i was wondering if you guys can educate me a bit and tell me if my hardware parts are compatible to each other.
I've managed to put together two sets of rigs, all according to my budget (1500$).

First rig:
CPU:
AMD Phenom II x6 1090T Black Edition  =    $180
Motherboard:
ASUS Crosshair IV Extreme 890FX   =     $250
Power Supply:
CORSAIR AX1200 1200W, 80 PLUS Certified      =       $280
Memory:
CORSAIR XMS 4GB 240-Pin DDR3     =      $54
Graphics card (Only one card in this rig):
Gigabyte AMD Radeon HD 6990 (GV-R699D5-4GD-B) 4096MB PCIe x16 Gen 2.1 Eyefinity 6 Edition       =      On superbiiz.com -> $725 (no where in stock)
Storage:
Western Digital Caviar Black WD5002AALX 500GB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive     =     $60
DVD:
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 - OEM   =   $20

Total = 1569$


Second rig:
CPU:
AMD Phenom™ II X4 955  =  $113
Motherboard:
msi 890fxa-gd70)   =   $195
Power Supply:
Antec CP-1000 1000W, 80 PLUS Certified     =      $135
Memory:
G.SKILL Ripjaws Series 4GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)       =       $41
Graphics card (two cards with crossfire):
2 MSI R6970 Lightning Radeon HD 6970 2GB     =       $387  X  2  =  $774
Storage:
Western Digital Caviar Black WD5002AALX 500GB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive     =      $60
DVD:
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 - OEM   =   $20

Total = 1378$

What do you think? which one of those rigs should i buy?
Do you i need to take other hardware? can you recommend me of an alternative?
1000W power supply is enough?

Any suggestions will be appreciated.
Thank you

Looks good id say you could even have one mining and one for gamming

Without looking through every part, my first suggestion would be to read through https://en.bitcoin.it/wiki/Mining_hardware_comparison and get a feel for price:MH/S comparisons. Your current builds would be nice miners but might be more expensive than necessary. Currently, 5830s are a great buy if you can find them. Also, try checking out http://bitminer.info/.

Of course, all that is only relevant if you're going to be mining with the rig.

I'd probably pick the top rig, because you can always expand by throwing in a second card. You can't do that on the bottom rig.

Are you using these solely for mining or as a regular PC too?

I would also go with the first one, heres why:

The 6990 card alone can do the same as the 2 6970s in terms of Mhash/s (give a few tweaks here and there). Also powering one device as apposed to w will be less heat/power consumption. You also have the option of getting another 6990 later on if you want to add into it.

My only issue with both machines are they seem a tad expensive. If they are just miners then you can probably cut down on the motherboards and CPUs - ie not get such fancy ones and save some cash.

well if they are for gameing to he will want the nice motherboad and cpu + the ability to add multiple cards should he decide later on

Why not?
Can't i buy later on another 6970?

I agree! But to tell you the truth... the only reason why i've writen the 6970 in my rig alternative specification is because i've been looking all around the internet and i cant find an "internet shop" that sell the 6990.  Apparently all 6990's are "OUT OF STOCK"...     Do you know where can i find one (or even two)?

Thank you all for replying so quickly.
