Concerned with heat i5/i7 build

My main question for a build is dealing with temperature. If I'm worried about heat since I have a small room and air doesn't circulate that great. Should I go for a i5 750 or i7 860 build for their lower wattage vs. a i7 920? Also, I figure if I go i7 920 route, I would eventually go sli/crossfire route and also need a larger psu, increasing heat and noise, with the lynnfields I would just get a nice single gpu. How much more heat could I be expecting? Thoughts? If I could make a computer thats low in heat and noise and going with the 920 route, I would lean towards that instead. I've already read a lot of the posts so have a general idea of what I'd get for each build.

APPROXIMATE PURCHASE DATE: 1-2 weeks

BUDGET RANGE: ~$900 After Rebates

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: watching movies, gaming, school work, surfing the internet

OVERCLOCKING: Yes
SLI OR CROSSFIRE: maybe, depending

MONITOR RESOLUTION: currently 1680x1050, maybe upgrade in future

From a cooling point of view, you could use any of the three, and performance would be comparable.
Since the i5-750 is the cheapest, and you are on a budget, Go that route.
Add in any of the top 10 oem coolers, and you will get adequate cooling. along with reduced noise.

With the launch of the 5870 you have a vga card that can run anything out there well with a single card, even at a higher resolution.
No need to plan for crossfire as an upgrade. You only need a psu with two 6 pin pci-e connectors, which will be about 550-650 watts. Look for a unit from corsair or PC P&C. Such a psu will not use any more power than it needs, and since they are relatively efficient, you will not generate much heat or noise.

What is your ambient temperature since you are so concerned about heat.

Why_me suggested a decent build.

You do want adequate cooling, but the cooling of the PC is not going to change the heat generated. Even if it's water-cooled, the total heat of the system will not change.

The only change you can make is the efficiency of the parts. A very efficient PSU will help. The GTX 260 is a fairly efficient GPU and so a good choice.

I think a nice efficient Antec PSU might be the better choice here though.

Don't OC beyond the stock voltage if you are trying to keep the room cool.

Thanks for the replies, my house is usually cooled to around 76F, we don't keep it too low so heat generated from the computer is fairly noticeable after long hours of operation. The build seems reasonable to me, I will probably gather most of the parts together and wait and see where the dust settles with the latest gpu announcements.

To Proximon:
Thank you, good information to know, I haven't found much regarding this topic. A friend was telling me mainly the cpu and gpu would be generating heat but I wanted to know more about that.
