Building/upgrading question

I have a HP a6620 tower that my dad gave up on because it was "unreliable."...just had a bad RAM card. Anyway, it seems like as good a tower as any to learn some PCing on. It already has Windows 7 HP, 64bit. I already picked up a graphics card with s-video so I can use it as my multimedia machine (of course, when I upgrade TVs one of these days, I'll get a better card w/HDMI). I'm going to pick up some more ram (replace the bad one and bump it up a bit) but am also looking into a better processor. It's currently sporting a 2.5GHz Dual Core but would like to go 2.8+GHz Quad for video conversions (kills the 2.5) but don't know what I need to get. There are two different socket types?? If so, how do I know what's what? I'm currently looking at the Intel Core 2 Quad Q9550...this seem like a good processor or does anyone have any recommendations? I'd like to stay around or below $300.

Any help/advice would be appreciated!

If your goal is video encoding, you will definately reap the benefits of a quad core.

the first this you should do, is go to HPs sites and look up that PC.
http://h20180.www2.hp.com/apps/Looku...&h_query=a6620

At the site they list several diff. versions of the a6620.
a6620a a6620at etc ... However looking at the a6620a

Socket 775/ 800FSB E2220 65W
G31 Chipset
MAX 4GB Pc6400 RAM (2x2GB)
PSU: 300W

E2220 is a 65nm CPU. You "might" be able to upgrade to a Q6600 if you can find one, and would be the easiest way.
Unless the board supports 45nm. A Bios upgrade may be needed for 45nm CPUs
i didnt see any info listed at the site if it does or doesnt support 45nm .. Ill look some more

Ok, found some info on that board.

Looks like it will only support up to a 65W CPU, which limits it to a dual core. Perhaps others may have something better to share.

You may not be able to run a quad on that board ..

The Q6600 is easy to OC - up to 3.4GHz on air. But it is a 95 watt unit.

Hmmm...this shows my noob-ness and I'm glad I asked before buying. I didn't realize the mother board may not handle it.

It is an a6620f..."Intel Pentium Dual Core E5200 / 2.5 GHz" also says 775 Socket and 65w. So that means I just need to take the plunge and get a different mother board??

just be aware that your OS license needs some "massaging" if you change the mobo.

I was considering starting fresh with a Professional version, anyway. I may be able to get another freebie license through MSDNAA. The OEM OS has all the HP bloatware that I'll never use...

You can maybe look if theres a bios upgrade that specificly adds Quad Core support. Sadly, many Pre-Built systems have the MOBOs locked down.



Depending on your budget, You could likely get a decent micro board that will handle a quad and 4-8 Gb RAM at a decent price,
and re-use the case/ HD

If your going to add a lot of extra I would consider getting a better PSU as well.

A dual core will still do a decent job with video encoding. Especially with DVD material.

It wont really start choking untill you're dealing with high bit rate 720/1080P content & using higher motion-search vectors etc..

The RAM isn't an issue, as the factory board can handle 8GB. I am going to have to reconsider this venture...

Side note, though, I'm currently using my Vaio (in Specs) for all my ripping/conversion (2.4GHz Dual Core) and it's doing fine but as with the HP, when trying to do file conversions (ie, I rip to avi for computer watching but convert to WMV for my Touch Pro 2) it keeps both cores pegged and takes about 1.5-2hrs to convert an average movie.

A Quad is definitely an advantage for file conversions although my Q6600 keeps the cores also pegged - but it takes less time than on my 4800+ (2.5GHz Duo). But 2 hours is a lot. I use Format Factory and that seems to be a little swifter.
