Hey there, I'm currently running into issues with my I3 4130 while running crossfire with two Sapphire vapor-x R9 270x's. CPU usage is generally at 98-100% when running games such as battlefront 3/ battlefield 4 whle GPU usage is averaging 70-80%. I'm experiencing low fps, screen tearing and flickering textures when crossfire is enabled. But the games run perfectly fine when only one card is used.

With just one GPU, the CPU generally sits at 60-70% so it's leading me to believe that the CPU may be a problem. If this is the case, are there any relatively powerful cpu's in the $200-300(AUS) range?

Cheers

There is really only two choices in your budget, the i5 4460 and the i5 4590 at nearly $300. How old is your motherboard? What version of BIOS do you have? You may need to update your BIOS to run the Haswell Refresh ships.

If you want to spend a little more you could get an overclockable i5 4690K.

AFAIK a new i7 4770K is not available for anything like $200 - 300.

This is bottlenecking due to the games stated use 4 cores and as your current CPU is duo core Hyper-threaded its able to run these (Just) but it cannot handle the game + 2 GPU's due to you playing this type of game you will need at least the I5-4460 or preferably a Xeon or I7 chip maybe a Xeon 1231 V3 or the I7-4760 (K) this is really up to you and how much you wish to spend.
