I'm a noob needing help !

[CallumCowley]

Hi, I have created this topic as I am in need of help and don't want to screw up, I want to upgrade my graphics card because on GTA V it get a maximum of 25FPS on the settings I would prefer. I think it's my graphics card what needs upgrading, as I said in the title I'm a complete novice. Here are my specs on my current build

Cooler Master CM690 II case

950W High Efficiency G7 Extreme Modular Super Silent Power Supply

MSI B75MA-E33 Intel Motherboard

i7-3770 Quad Core Processor 3.5Ghz

3GB AMD RADEON HD7950

2TB SATA III 6Gb/s, 7200rpm, 64MB Cache, 8ms Hard Drive

As I said I don't know what to do to help my FPS , I've tried using AMD overdrive and yet still had no avail, if any parts are in need of upgrading my price range is about £300-£400, any help and tips would be greatly appreciated.

Well the only option is upgrade PSU (that one sounds horrific) and upgrade GPU, the CPU is still very strong

 

What temps do you get when running it?

[CallumCowley]

Crap, got the wrong wattage on the PSU ahah sorry, it's actually 950W, and so I only need to upgrade my GPU, could you perhaps give me a suggestion for my price range ? And by temps I assume you mean temperature, and when playing GTA for around 30 minutes the temperature of my GPU is around 50-60 degrees Celsius.

Is it this thing? - http://www.amazon.co.uk/HEC-Compucase-G7-Modular-Extreme/dp/B008O0VT08

 

Also, what temperatures does your CPU get up to?

[CallumCowley]

After about 15 minutes of gameplay it's about 32 degrees Celsius in each core,

and yes that my power supply.

Update: I've been searching around and a GPU what seems to be around my price range is the AMD radeon R9 290X, would this work with my build, or could I get a GPU what suits my build better, and improve performance even if slightly more expensive ?
