Hello, okay I will be doing this eyefinity build for the next 6 months. I'm thinking on getting these components.

Intel Core i5-3570K 3.4 GHz
Cooler Master Hyper 212 Evo
ASRock Z77 Extreme 4
Corsair Vengeance (Dual) 2x4gb ddr3 1600 CL9 (CMZ8GX3M2A1600C9)

Sapphire HD7870 Flex 2Gb
Intel 330 Series 60GB SSD then add Western Digital Caviar Black 1.0 TB later
Cooler Master Elite 431 (I'm sure this is quite enough)
Corsair TX 750 Bronze PSU

and 3 24” Viewsonic VX2450 / VA2448 monitors.

I will not be OC'ing right on but I know I would have to in the future.
Can think of only using it for games
Won't be adding more HDD's but thinking about the possibility of Crossfire in the far future.

I just want to know if these are enough! Im not really interested on spending more on something I wouldn't really be needing right on!


and if there's something I also need to consider that I ddn't mention here please say so!

Thanks in advance :)

It's overkill....you can easily power the 7870 with a 550W if you wanted to.

For crossfire, a good 650W will be the best choice. Get the TX650V2!

Thats really good to hear. cause I just read the 750w in other forums for plenty of headroom they say. Thank you so much :)
