The 2.5 GHz model is 160$ on Newegg.

There are ways to get student discounts on Win7, those are probably the cheapest you'd find.  Just Google it or something.

The E6420 is more than powerful enough to run Win7 64-bit. It is, however, pretty weak for games. You could easily upgrade to a mobo + CPU combo that would blow that one out of the water for about $150 if you wanted to - just wait a few days for the Athlon II X3 440 to show up and grab an AM3 or AM2+ mobo that supports your RAM along with it (I'm assuming that you're using some flavor of DDR2).

Either way, I wouldn't buy another LGA 775 CPU. The standard is pretty much dead by now, and any CPU that uses it is overpriced for what you'll get. AM3, by contrast, will let you upgrade to a new mid-range CPU in two years without replacing your mobo.

@ jefforange88: Good idea on the PC gaming misconceptions! I'll add that in the next major revision.

is this any good for the price, I intend in using it for medium gaming. (keep in mind the price is in canadien dollar)

cpu: Intel Core 2 Quad Q8200(2.33GHz)

gpu: NVIDIA GeForce GT 220

memory: 4GB (2 x 2GB) PC6400 DDR2 800 Dual Channel Memory

os: Windows 7 Home Premium 64-Bit

I wouldn't buy it, the GT 220's pretty awful.

EDIT: Also, it has a pretty terrible PSU, which doesn't really give you much room for future upgrades.  And moreover, since the Core 2 line's completely dead now, there won't be anything new coming out worth sticking in it in the future... which might not really matter to you, but it does mean that if you want a better CPU in the future, you'd have to buy a new motherboard, and along with it new memory as well.

Don't buy from Cyberpower, iBuyPower, or any of those "cheap gaming PC" pre-builts. They're almost universally crap, due to the builders cutting corners with cheap, older, or underpowered parts. In this one, here's the immediate problems that I see:

1) The Core 2 Quad is outperformed in most games by the $90 Athlon II X3 440. It's also on LGA775, an obsolete socket.

2) The GT 220 is not a serious gaming video card - it's outperformed by a $50 Radeon 4650.

3) DDR2 800 is an older RAM standard, meaning that you'll have a tough time upgrading in the future.

4) The power supply manufacturer isn't listed, so I'm willing to bet that it's cheap and will fail on you within a year.

5) All that being said, the mobo is almost assuredly an obsolete model as well.

6) No digital optical audio out, nor even support for 5.1 analog. Any half-decent mobo will include both of those things.

7) The case is cheap, (IMO) ugly, and has two 80mm fans, meaning it's almost guaranteed to sound like a jet engine while running.

Basically, a prebuilt gaming PC manufacturer cannot undercut Newegg without sacrificing quality.

That said, if you let me know your budget, your monitor's display resolution, and anything else you'd like to do with the PC besides gaming, I can try to spec out something for you that would fit.

I got 600$ (including os)

I will use my old monitor ( my resolution right now is 1024x728, but it can support higher resolution) for now but I will buy one like this one later:

Most of my gaming on pc will be with rts games, I also want something I can update when my budget loosen up a little bit.ALso I never built a pc myself so, if the products are easy to put together that would be great.

Also I just want a fonctional case, no fancy stuff

PCs are easy enough to put together, if you can build a desk or something, you can build one.

Unfortunately, shopping on Newegg.ca, if you don't get free shipping, things can get a bit costly - what province are you in, looking in to local retailers is always good as well. I usually try to only buy from Newegg if there's a large price difference, or if there's free shipping.

I live in Quebec inthe city of montreal, which is a big city, but I can't find any trust worthy shop that specialize in computers, and I don`t want to buy from bestbuy or future shop

Ah, can't help you there, I would have told you to use the store I shop at, but they're Ontario only. :P
