I have the HP D4100y. The case is huge. It has like 4 Disk slots, like 3-4 HDD slots and the MOBO in it at the moment has 1 PCI-E X16 slot, 2PCI-E X1 slots, and 5 PCI slots.

My Case is HUGE!!

How can I tell What kind ofForm Factor is actually in my PC?

On the HP support site, it says the MOBO in right now is a Micro-ATX 9.6" X 9.6" It also has a PCI expansion slot that has an addition2 PCI slots making the total 5 slots.

I am wanting to upgrade my MOBO so I can get an E6600 C2D. I am looking at getthing is aGigabyte GA-965P-DS3http://www.newegg.com/Product/Product.aspx?Item=N82E16813128042

It says that the MOBO that I want to get has a Form Factor ATX 12" x 9.6"

Should it still be able to fit since my case is huge? I'm just thinking that it currently has a small MOBO in it at the time but it should be able to fit a larger one. It has an expansion slot added to it at the moment so I think it would fit.

I just want to upgrade but am now worried that it won't fit. Please help if you have any advice.

Thanks

What is better for games? Intel E6600 or AMD 5600X2?

Thanks.

It has 2 sticks of 512.

I already have 1 gig of DDR2 ram which I think is 533Mhz (it came with my HP so i bett it's not the higher end.) WI am wanting to get 2 gigs of ram. Would it be smarter for me to just get an extra gig of 533mhz of memeory, or quit using that ram and spend a lot more on getting DDR2 800mz ram? Would I notice a big difference in games?

Thanks.
