Best budget computer for photoshop CS4

Hi guys I am doing an uprade.

I have an Antec sonata III case I want to keep and an optical drive. other wise I need to buy everything else. my budget is 600 pounds, and the usage is mainly web, and photo editing.

Does budget include OS? Monitor? Keyboard? Mouse?
How about PSU? Still have a good Antec 500w in it? How old? They are a dependable little unit so I would not replace unless you really need to for some reason.

Here is the sticky mentioned above that lists the information that is helpful:

Also are you interested in gaming or hi-def video at all? If not, you can get by with onboard video. If you might be - a cheap $60 to $70 graphics card would be a nice addition. It makes a difference in mobo choices too - but not so much the price - you have better selection without onboard video.

Your budget should be more than ample. I am not familiar with UK stores and prices so I used US for both – assuming you can find something comparable – and stayed way under budget to allow for higher prices if necessay. Until you answer the question asked in a previous post about what all you want to include, for now I just included the basics:

CPU -Intel Core i5-750 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor - Retail $199.99

Mobo – go with Gigabyte or ASUS – similar price and only minor differences.
See this review of mobos.

On the last page summary its states:
None of us buy based solely on overclocking, one or two percent performance differences, or a few percentage points in efficiency. Rather, it’s the combination of overclocking, features, and performance that gets us ready to spend our money. For $10 more than the P55-UD3R, Asus’ P7P55D offers IEEE-1394 FireWire and slightly better overall efficiency. Gigabyte, on the other hand, offers a third SATA controller and supports Windows XP users with a floppy interface--all for $10 less. These two products are as close to perfectly-matched competitors as we’ve ever seen, so we’ll let you, the reader, make the call.

I prefer the Gigabyte so I listed it (note that it does not include onboard video:

GIGABYTE GA-P55-UD3R LGA 1156 Intel P55 ATX Intel Motherboard – Retail $139.99

Memory - there are a lot of options and I don’t know how prices run in UK. But based on what is available here, I suggest:

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRH - Retail 94.99

Hard Drive
Seagate Barracuda 7200.12 ST31000528AS 1TB $89.99

Basic Grapics Card
GIGABYTE GV-R467ZL-1GI Radeon HD 4670 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail $69.99
http://www.newegg.com/Product/Prod [...] 6814125277


Total $ 524.99 or converted it is GBP 322.22

The above should give you a good baseline starting point at least - and a good a system as it.
What needs to be added: Operating system? PSU? Faster graphics card? Monitor?

If you can afford a little more, you might upgrade the CPU to an i7-860 to benefit from hyperthreading. But with 4 cores in both this and the recommended CPU, I am not sure how much you will gain. You might want to look at this review on CS4:
