PSU then GPU.

Sorry for being a noob but what is a PSU? Also could you go into a bit more detail?
EDIT: Ok so you mean Power supply unit. How would that improve gaming? Also what GPU?

A new PSU doesn't improve gaming, but is required to power a new GPU which will.

If you want specific suggestions post your budget and the games you want to improve performance on.

Your model comes with a 300w PSU which is of poor quality so wont handle any decent cards. Your CPU is perfectly capable but in order to play better graphically demanding games you will for sure need a better GPU.

Ok, what would it take to run the best games on highest graphics? I personally don't have a lot of trouble because I dont have many games, however I do have to run tribes ascend on low/medium graphics. Also if the card I requested is a lot, what would recommend that is value for money? Oh and USD is fine I just want an aproximation.

If it fits in your budget you will need to grab a Corsair 650w TX PSU, then depending on budget either a 660ti or 670.

Could you get anything decent for say $300 - $400? Oh and I forgot to put my card specs in the first post, I have an AMD Radeon HD 7450 1GB if you were wondering.

 

[PP Mguire]

You would have to check the prices for the sites or stores that will sell to you. Here in the US the 670 is less than 400 and you can get a Corsair 650TX for about 69 bucks.

Over here the card is about $450 and for some reason the PSU is about $200

Seems a bit much, am I looking at the right things?

For some reason its saying I need to wait for a mod to approve my post, I think it might be because I had links. Lets see if that was correct
EDIT: Ok it was, so I found the gpu for about 450 and the PSU was like 200 for some reason... not sure why. I noticed in another post you suggested the 560 ti or 650 to someone. Would either of those be any good?
