Right now I'm running a Asus HD 7850 Direct CU ii, I was wondering if it would be worth it to Crossfire this with another, or to just get a new card all together, will crossfire give me the same performance as a high end single GPU. Whats the pros and cons?
What motherboard do you have? Crossfiring does not usually scale 100% meaning you won't double your performance by adding another 7850, though with a great deal it still may be worth it. However usually I suggest selling the old gpu and getting a better single card as there are always chances of additional problems being introduced with sli/crossfire.
Well your MOBO is fine for CF support, I don't know what your PSU is but again it is just a matter of whether the possible hassel/less than 100% scaling is worth any savings you may have over buying a better single card.
If I were you I would try to sell the one you have and try to get a 770 or better.
Intel Core i7 4770k 3.5ghz
Asus HD 7850 Direct CU ii (overclocked) from 860 mhz to 1000mhz
Seagate HDD 7200 RPM 1 TB
Kingston V300 SSD
2x4gb Corsair Vengence Ram 1800mhz
Generic CD/DVD Rom drive
TP Link 300mb/s Wireless card
H80i Watercooling loop (x2 fans) on radiator
3x Case fans
Also Power Supply is 600w and not bronze+ certified or anything so proabably gonna replace it and do you think that this Graphics card is bottlenecking this build?
