Is my Radeon 4870X2 bottlenecking my rig?

Here is my build


Mobo: Asrock z68 extreme3 gen3
CPU: Intel Core i5-2500K Sandy Bridge 3.3GHz
Ram: 8gb G.SKILL Ripjaws X Series DDR3 SDRAM DDR3 1600 (PC3 12800)
Graphics Card: Visiontek Diamond Radeaon HD 4870X2
PSU: 750w Coolermaster
Case: Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case

Some games run pretty well but others, like trine 2, chug a bit. I figured a game like trine 2 would be easy for my rig to handle at max but I need to drop to 1400x900 res and very high settings to get a stable frame rate. Should this be expected or is my graphics card the culprit? Is it time to replace the old card? I don't have issues with noise and overheating really, so that isn't a factor. Any input would be appreciated.

Also my hard drive is a sata 320gb Seagate @ 7200rpm. Not sure if that info is necessary though.

Some games don't scalling to good on SLI or Crossfire setup.My opinion : is time for an GPU upgrade. The newest games are more hardware ( gpu )demanding.

Hmm, any suggestions on a new card? I see you have an MSI 6950, is that about today's equivalent of a 4870x2? I don't need resolution any higher than 1920x1200. I'm kinda hesitant to go with ATI again because of their poor driver support of the x2, have they gotten better in this regard?

from the hierarchy chart:
Discrete: GTX 590 Discrete: HD 6990

Discrete: HD 7970
Discrete: GTX 580 Discrete: HD 5970
Discrete: GTX 295, GTX 480, GTX 570
Discrete: HD 4870 X2, 6970

Discrete: GTX 470, GTX 560 Ti, GTX 560 Ti 448 Core Discrete: HD 4850 X2, 5870, 6950

So you see your system is up there. Make sure your drivers are up to date - may be a slight cpu overclock is in order.

4870x2 is still that high? I had hoped a $500 card would have some staying power. I may try a slight overclock since I still have a stock cooler on my i5. Maybe I will try 4.0ghz

Thanks for the info

You would be much better spending the money on a SSD, that 7200 RPM HDD is severely bottlenecking your system as well. On the contrary to most other upgrade, you will actually notice a huge difference in everything that you do (other than the actual fps in games) when you upgrade your regular HDD to SSD.
