Hello, I'm from Portugal and I'm currently building a new PC that should be around 1000€ (i know i need to cut some things). I need to know if all the hardware goes well together and if you have a better suggestion for any of them.  
Also I need to know if the PSU is enough (450w) and if the cooler is needed.  
My main activity is photo editing and a little bit of gamming.  
 
CPU: Intel Core 2 Quad Q6600 230€  
Motherboard: MSI P35 Neo2-FR 100€  
Memory: Corsair 2GB PC2-6400C4 XM2 DHX 100€  
Video Card: GeForce 8800 GT 256mb 200€  
Display: HP LP1965 320€  
Storage: WESTERN DIGITAL 250 GB 16 MB CACHE SATA II RE 79.95 €  
Cooler: TUNIQ TOWER 120 40€  
Power Suply: Corsair 450VX 80€  
 
Thanks in advance.

Yep, an 8800GT pc will require 425W 28A on +12V's. That's a good psu. If you're going to overclock, you may want a different mobo like the GA-P35-DS3L/R or P5K.

The 19" screen is a strange choice for photo editing.  
Also quite small for a 8800GT (but that's good for eye candy).
The RAM is quite expensive.  
So is the WD RAID EDITION drive for a no RAID board.

Thanks for the replies!
I've changed the motherboard to Gigabyte GA-P35-DS3R like it was suggested thank you.
 
Still need and alternative to the memory since that corsair is too expensive. Need 2gb at least
 
Also can you make a suggestion of an alternative to the 8800GT in the same price range?
 
 Do I need the cooler I picked up?
 
Thank you guys

If you're not overclocking your CPU, there's not point to getting that cooler. You can probably get a much better 19" monitor for a lot cheaper. If you shave the money off of the cooler(40), about 80 off of the monitor, you can upgrade to the 8800GT 512MB which is a much better choice. Unless you aren't doing any gaming, then I would stay with that.
 
What site are you buying from?

I'm going to order from different sites the parts and assembly myself.
I choose that monitor because of the good reviews it had. I need an acceptable for photo edit but not that expensive. Can you suggest me a better one then? (non widescreen)
 
What about the memory. Any ideia of a good one?
 
I'm probably not going to overclock it.

Any brand name 800mhz ram is fine as long as the pc isn't overclocked. You might want a kit with heatspreaders.

Thanks for the replies guys.  
I made some changes based on different replies and a little more research.

I dont plan in overclocking it.
1)Do I still need a cooler?
2)Should I pick the G.Skill or the Corsair?
3)Is this PSU enough for the system?
 
Thanks

1-You won't need the cooler unless you're overclocking which you said you weren't
 
2-I would go with the Corsair, I've heard they're a much better brand than G.Skill
 
3-That is a very good line of power supplies. Im not so sure if this is enough, maybe a 500 or 600 watt is better.

Ok, you're worried, a retail cpu comes with a cooler. Don't waste your money unless you overclock.
 
Like I said above, 8800gt pc uses around 425W. If you have the money, get a bigger brand name one.
