Advice needed on old pc upgrade

I have an old-ish PC from around late 2010 that I want to upgrade, however being a university student I can't afford to pay for all of this at once. I've decided on the parts that I want, but I want some advice on the best order to replace the parts.

The parts I want to replace are the CPU + MoBo, GPU, PSU, and Case, which are as follows:
Intel Pentium Dual Core E7500 3GHz
Nvdia GeForce GT 520 1gb (DDR3)
Cheap brand 450w PSU
(Front ports on case are damaged, USB headers and audio jacks, from moving it around. Plus has poor airflow, only supporting 3 fans, and seems to suck in a lot of dust)

The parts i'll be buying are:
AMD FX 8320 (£105)
Asus M5a99fx pro r2.0 (£90)
HD 7770 (£85) (or 7850 if I can afford it) (£100+)
Corsair CXM 600w (£50)
Zalman Z11 case (£45)

(These prices are from amazon/ebuyer)

Either way i'll be upgrading the case + psu straight away. What I want to know is with the leftover money will I be better of buying the CPU + MoBo or should I go for the GPU first? Or are there similar performance components that are cheaper?

I was considering swapping out the 8320 for an fx 6300 as its around £30 cheaper but how much of a performance difference would there be between the 2?

I use my PC for some casual gaming (I play mainly older/indie/simulation games but I have some new ones on my steam list that I bought on sale like Tomb Raider, Far Cry 3, Batman collection, Deadfall, Witcher 2 which I want to play as well). I also do a bit of programming, mainly in Java although soon I will be starting a project using actionscript that will involve some graphic rendering and using photoshop etc.

Thanks in advance for any advice offered.

  1. I would suggest u keep the fx 8320. Another thing, can u tell us the amount of money you are currently going to spend, so we can help u out with the components.
  2. At the moment I only have around £300 to spare, considering the case and psu are going to set me back around £100 that gives me £200 to either spend on the CPU/MoBo combination or to spend on the GPU with money left over.

    I suggest you upgrade that GPU first. Sure, you will have a dual core CPU, but you will at least be able to play games on medium.

    However, keep in mind that you will need to upgrade that PSU.

    May I suggest a GPU and a PSU:

  4. Funny that you should bring up the R9 270x, I was looking at these yesterday, albeit the 260x, after reading the Tom's Hardware article "Best Graphics Cards For The Money: May 2014" . I became especially interested in this range when I saw there is a promotion in which, from some retailers, you can get a code for up to 3 free games, including some im interested in, giving them even better value.

    So very good recommendation, cheers!

    PSU looks good and I like the XFX stuff as they mostly seems to get good reviews for build quality and reliability. Might be a bit out of price range but if i'm not going to be getting the CPU/Mobo for a few months an extra £15 isn't much of an issue.
  5. Glad I helped!

    I would suggest you upgrade the CPU/Mobo as soon as possible to get the full potential of your PC.
