7870 not performing correctly or something else?

I recently bought and XFX 7870 Ghz ed. (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) and a SeaSonic S12II 620w (http://www.newegg.com/Product/Product.aspx?Item=N82E168...).

Rest of specs: CPU: Intel i3-2120, RAM: 8GB 1333 mhz

After getting them both installed I began testing out my gaming performance relative to my HD 7750 that I recently used. I have noticed improvements in performance in all games but I feel like I should be getting more. I play at 1360x768 until I buy a 1080p monitor sometime hopefully soon. I tried playing Metro Last Light fully maxed out and was barely getting 30 fps(Very High w/o SSAA and tessellation would be 50 fps+ with some drops), fair enough I guess. I also tried playing Far Cry 3 and was able to put around high stettings with some ultra and get 50-60 fps pretty constantly. With my HD 7750 I could play Metro LL and Far Cry 3 on medium-high settings with around 45 fps but with my HD 7870 it seems like I am struggling to get even twice the performance of a low end card.

(tl;dr kinda) So I was wondering if my CPU could be holding me back or if my PSU isn't working properly (severely doubt it) or could I just have a bad GPU? Or could it be my performance is normal and I'm just expecting too much?

Edit: Also just to add I am having a problem of massive random drops in games like Fallout 3/NV and Skyrim where my frame rate drop from flat 60 to around 45 and to 30 for what seems like no reason at all.

yes the i3 hold some performance, my last i3 i have is running at 3.6ghz. and getting some bad fps with 670. i changed it for the 3470 running 4.0ghz working like a charm.

I was actually looking into getting a 3470, so I am guessing that you are saying that getting a 3470 should solve my problem?

definitely the i3 is holding you back. Still a nice cpu that goes well with the HD7750, but if wanting more performance out of a more powerful card, an i5/i7 is better suited.

The 3470 is a nice cpu and is newer architecture (Ivy Bridge) but lot of Sandy Bridge era motherboards require a bios update to run the newer cpus using the same 1155 socket.

Your current i3 cpu is Sandy Bridge which your bios may need an update from the manufactures website to accept Ivy Bridge cpus, which they should as most do, so that shouldn't be a problem, just need to check first before considering a 3470.

Personally would consider getting the i5 2500k(Sandy Bridge) Quad core with unlocked multiplier and is in the same level of performance as 3470 albeit 2500k using little more power and will work natively without an bios update. Either cpu crushes the i3 and will be a great addition coupled with your 7870.

2500k having an unlocked multiplier can easily be overclocked with an aftermarket cooler.

Also, is that 1x 8Gb memory? upgrading to 2x 8Gb will also improve system by enabling dual channel memory when the system has even sets of memory installed.

Ok I didn't know about the bios update thing so thanks, also I will not be overclocking so that is why I was gonna chose the 3470 because I am not much of an overclocker, even with GPUs. Also I do use 2x4GB RAM so I'm good there. Thanks for the advice regardless.
