I would suggest the 760GTX card. AMD wont perform as well as Nvidia with Premiere right now. The 760GTX will be more than enough for that system. You will also need 16GB of ram to really make use of the GPU upgrade.
The biggest improvement you could make with that system would be to upgrade the CPU to a hyper-threadable processor like possibly an i7-3770K, That and memory and a moderate priced nVidia CPU would make all the difference in the world
....unfortunately, its time to call HOSPICE and prepare for burial of your aged rig. FORTUNATELY, the new Haswell E is due out in the next few weeks.... this new CPU is going to bring many significant improvements with it, that will enable buyers to " future proof " their PC for AT LEAST six months !!! Faster quad channel memory, 6 or 8 core versions that can OC over 4GHZ, 10 onboard SATA III ports, etc. As Paul Revere yelled : " 4K is coming !!!...4K is coming !!!", Haswell E would be someting to think about...
I think I agree with you Bill. The most visible bottle neck I can see is the CPU when editing, playback almost always uses 100% of the CPU. Though I don't know how much benefit a GPU upgrade will bring because I can't see the performance of the GPU and where it's suffering
By the way I don't need to render much and I don't export at all. All I'm after here is real time playback.
The footage is DSLR 1080 mainly. Editing multicam and somewhat heavy on filters.
Should I upgrade the CPU and forget about the GPU for now?
That would possibly mean I have to upgrade/change the motherboard if the CPU isn't 1155 socket
I'm budget conscious
Appreciate the help!
Edit: Here's a list of Hyper-threaded CPU's which are 1155 sockets.
I went ahead and bought a i7 4470K!! I found one for $300AUD which was a good price for an (open box)
Thanks Bill for making me spend more money on something I didn't think I needed
Now I'm on a hunt for a cheap motherboard that will allow me to OC this baby to at least 4.5Ghz
What do you guys think I can get away with?
There is no such processor as an i7 4470K. Did you mean i7-4770K? You need a Z97 chipset, here in the US, they start at $90 but you may want to figure out what other features you need. If you want to overclock look at the Gaming boards or those specified for Overclocking. Make sure you have a good power supply for overclocking.
