So it has soon been a year since i built this computer, and i'd like to add two more monitors to it and upgrade the GPU and after researching i decided to go with a radeon 7990. But how good will games run on three benq gl2450hm's with it? Or should i go with a different GPU?

CPU:Intel core i5 3570 3,4 ghz (overclocked to 4,0 ghz)
CPU cooler: Cooler master hyper 212 evo
Motherboard:Asus p8 z77-v le plus
SSD:Intel SSD 60gb (For OS)
HDD:Seagate barracuda 2 terrabyte harddisc
RAM:Corsair 16gb xms3 1600mhz 2x8
Power supply:Corsair tx 750W m
Case:NZXT phantom 410
OS:Windows 7 Ultimate 64-bit

With those specs, anything that's an HD 7950 and above would kill your Eyefinity setup. I don't think you'll have any problems other than making sure your PSU is enough for the job. A single card won't cause as much problems as when paired with another. Also 6GB? Damn.

RIGHT! Pretty penny for one of those eh? i imagine its 384-bit or even 512-bit?

Edit: correction 768-bit....348-bit x2....WOW that's a monster i would make sure your PSU can handle that seriously, maybe invest in a liquid cooling block for it to

The only single card that can match it is the GTX 690 and in all reviews it has the edge but the HD 7990 is less power efficient. Quoting Tom's Hardware, "AMD's highest-end GPUs draw power like there is no tomorrow (or at least like you won't have a bill to pay at the end of the month). They even manage to blow past the theoretical 525 W limit defined by the PCI-SIG electromechanical specification for three eight-pin connectors and a 16-lane slot". They have dropped the price of these cards considerably lately and they seem like a good deal but it just makes me wonder ....Why?

Yes i am a bit concerned about the PSU as it says that 750w is the required. I still got some money to spare so if it is needed i might get a new PSU too.

You could also wait for the AMD Radeon R9 290X 4GB DDR5 (512-bit). It will take hits when pitted against the HD 7990 but the other useful features it has could definitely win you over. 300GB/sec bandwidth isn't something to ignore. If you can spare the 2GB, then this card is for you.

Yeah i'd even go with a 1000w PSU to make sure everything is powered correctly, please don't go cheap with a PSU either you'll regret it.
