Please review config - first gaming PC

Hello,

I have been reading forum for a couple weeks now and am trying to fine tune a configuration for my next PC.

I have stuck with my Dell with a (ummm Pentium 4 ) for about 8 years now which I upgraded 4 years ago so I think I am ready for a real upgrade and DS is where I want to get my next system from.

My budget is around 2.5K. I want to be able to do gaming with modern games and have a 3 1/2 year old Dell 24 Inch LCD 1920x1200 monitor which probably has pretty poor specs compared to current stuff.

Questions:
1. Right now I don't think I would ever try SLI but I was hedging bets by upgrading PSU to 1200W. Is that worth it or or should I just save the money or put it elsewhere.

2. With plans for only a single monitor at that resolution am I at overkill using the 480 and could scale back to a 5850 without really noticing it?

3. Has anyone went with the LED fan or internal lighting upgrades with this case? Were you happy with the result?

Thanks for your suggestions!

Here is the configuration:

for a 480 you would want 1k watt not 750, 1250 is you want sli.

for your res your gpu is perfect, with a 5850 your going to be underpowered.

everything else looks golden

Thanks all for the feedback! I will stay with the 480 and the 1200W PSU go with both lighting options and not forget to check for the free gifts. I will post back when I have sent in the order!
