Need some advice on a £379 build ($611)

Hi

Recently i decided to build a new mid gaming rig with a budget of 600$, i curently live in england and im a game design student. I will be using programs such as 3ds max and photoshop quite often, i also will be playing a lot of game's due to be released in the next few months such as battlefield bad company 2 and diablo 3. What im after is a gaming rig that will alow me to play and work with high preformance, im not after amazing quality of graphics but also i would like to enjoy the visual aspects of the games that are to be released.

I currently have a 5 year old PC with a faily useable graphics card HIS Radeon HD 4670 IceQ 1 GB DDR3, 250 GB hard drive and a 500W PSU which i can salvage from my current machine. my budget is limited but i can afford to go up to £370-$600 for CPU-MOBO-RAM-CASE. I do not have much knowledge on gaming/preformance hardware that will match each other for example what to chose between i5 or Quad core. Because im a student i cannot afford to buy the wrong hardware and end up wasting my university loan. Im looking for some advice on what to buy and where to buy (the less i spend the better). I also wanted to know if Intel is better for gaming or the new AMD CPU due to my budget the less i pay the better.

I aplogize for the long read.
Thanks for your time.

4GB (2x2GB) Corsair Dominator DDR3, PC3-12800 (1600), 240 Pin, Non-ECC Unbuffered, CAS 9, DHX

Intel Core i5 750, s1156, Lynnfield, Quad Core, 2.66GHz, DMI 2.5 GT/s, 8MB Cache, 95W, Retail

Asus P7P55-M, Intel P55 Express, S1156, PCI-E 2.0(x16), DDR3 2200(OC), SATA 3Gb/s, SATA RAID, mATX

this is what i came up with on scan.co.uk all together for £399 inc vat and carriage

What about the other parts are they good enogh for that budget or will i be able to get the same preformance for less price

Another case to consider is the Antec 300 Illusion. It's like the 300, just has 2 extra blue LED fans in front.

I also like this mobo better for an AMD build: Asus M4A79XTD EVO 87 pounds. It's a little more expensive, but has PCIe 2.0 slots at 8x/8x instead of 16x/4x.

also for the i5 mobo and cpu which ram will suit the hardware?

Im happy to get AMD cpu as long as it delivers the game preformance im looking for

right i took ur advice on the AMD build and it saves me about 40 pounds i have 4 hours to buy the products so i can receive delivery tomarow. This is the current build

Xilence Red Wing 120mm Quiet Fan - 3&4pin connection

all of this comes to a total of £351.79 with delivery

Is this a good build for that price or should go for a i5 build?

This RAM is better: Kingston 4GB (2x2GB) DDR3 1333MHz HyperX Memory Kit CL7 1.7V

This board is more future proof: Asus M4A79XTD EVO. It's a tad bit more, but has the second PCIe slot working at a speed that will allow you to have the option to Crossfire/SLI later.

Rest is good. What's with the red fans?

the red fan was recommended, also im not looking to crossfire should just save money on that? and my power supply is 5 years old but it works fine would i need to get some diffrent wires for it? and my HD is SATA will it work with the mobo thanks

I have the connectors for the GPU so thats fine. this 50 pounds cheaper than the i5 build will this give me the same preformance as the i5 (in game's) or less? i also want to thank you for you advice and time

thanks so much for help, the hardware will be delivered tomorrow and when the build is done il post back some feedback on how it runs.
