how bout this case
antec nsk 2480
http://www.newegg.ca/Product/Produ [...] pk=nsk2480
will 380 watt enough for this build?
I have heard alot good things about antec lately and im impressed with my friend's antec 900

how bout the others?

thx for the fast reply first of all

i want the system to be able to run fps games say COD 4 at max graphic setting at 1080p. So my question is which gpu will satisfy me?and which side should i go for nvidia or ati?please include the reason if it is possible

will i be better off with say x2 545 which is $25 cheaper if this system will act as media server(my parents and sister wants to stream videos to their bedrooms)?
can u elaborate the "unlocking core" part? im kinda lost there

It's pretty accurate when used correctly. And when you understand about having the correct amperage distribution (that note on the Extreme Power Supply Calculator)

Which would make the Antec 380W PSU a fairly good match. PSUs are most efficient when they run in the range of 40-60% of rated power.

When a PSU is pushed hard it runs hotter and louder which is one reason you see recommendations to up-size PSUs. And that can be a problem for small, possibly under-ventilated HTPC type cases. Most perfer HTPC systems to be quiter.

Max graphics quality settings in some games at 1920x1080 is going to be a challenge for a 4850 or even a 4870.
For COD4 it won't be a problem. For Crysis - you'd have to turn the graphics down, maybe even to medium, to be playable at 1980x1050.

To stream videos (act as a server) is a fairly low demand on the system. For that task you could go a lot lower in the CPU and leave out the gaming GPU.

No; I think if you get a 380W PSU it should work out well for you. During a heavy gaming session you might start to notice the fan running louder, but you won't be pushing the PSU to its limit.

What you have chosen is much closer to a gaming system than a typical HTPC. You probably should check and see what the other people are saying about that case. Check the NewEgg customer comments and pay special attention to remarks about cooling, especially any who have hardware similar to yours.
That HTPC case does have 2 fans for cooling but you'll want to monitor your temps to make sure they are under control.

I think you have a pretty well balanced system. CPU/GPU match pretty well for 1920x1080 gaming - as long as you can back off the AA/AF setting and maybe live with 'Gamer Quality' in place of Max Quality for some of the more demanding games - like Crysis.
