It depends on the exact model of G72 you have. However, if you don't have an I7 now, yours problably doesn't have the right socket. If yours is the Best buy model, the one ending in 05 can only take a t9900 as the max cpu. It will not take a quad core (q9000,q9100,qx9300). The one ending in 09 came with a q9000, and will take a qx9300. the qx9300 is faster than a I7 720 or 820. In theory the I7 920 is the fastest cpu made, it's also unobtainable to mortals. As to the BB models, I tried a q9100 I got from Impactcomputers.com and it would not POST. I updated the latest bios, and tried everything . I did notice the 05 model was missing at least one phase of the VRM for the CPU which may explain why a 45 watt CPU wasn't working. It came with a P8700 which is a 25 watt chip.
 

I would say a with confidence NO, your's won't take an I7 because your asking, meaning you have a core 2.

I was able to pick up a cheap QX9300 from these guys. for $325

http://www2.bigblueonline.com/

These guys seem to have a lot of parts, and you can search for the CPUs
easily.  I've also gotten a good deal or two from Impactcomputers.com.

Now, I've bought the Best Buy model RBBX05 and could not get it to post with a Q9100 leading me to confirm that if it didn't come with a quadcore, you cannot upgrade to one later. This cost me a restocking fee, and I bought the X1 version from Newegg with the better screen (1080), Q9000 (went into something else) and 2 320gb drives (replaced by X-25m SSDs).

You can look at the rating of mobile CPUs here.
http://www.notebookcheck.net/Mobile-Processors-Benchmarklist.2436.0.html

In order from highest to lowest (based on 3Dmark06 cpu).
 Note that the X is 45 watt, the Ts =35watt, and Ps =25watt.
X9100
T9900
T9800
P9700
P8800
T9550
P9600
T9500
T9400
T9300

I'm assuming you have the p8700 which overclocks pretty well. For example, the P8700 scores 2231, where a P9700 is only 2552 at 2.8ghz. I was easily able to get the 8700 to reach that speed using the built in overclock function. It's a 25 watt cpu meaning at worst overclock it might hit 35 watts of a T series.

For $300, buy an SSD as your best money spent VS spending $200 or $300 on a marginal CPU upgrade.
 
For me, the jump from a Q9000 @ 2828 score VS a QX9300 @ 3750 or higher justified the cost $325 and I know I can sell the q9000 for that much making it a possible free upgrade.

I'm also upset to say the entire G72 series only has a non-raid capable south bridge. Without a reflow solder machine and a doner motherboard, there is no way around this limitation. The southbridge is the ICH10 not the ICH10R. The really crappy point is that the cost difference in parts is $3. Gotta love the bean counters for screwing this one up.

Barry, this is exactly what I was looking for- thanks so much. I know it's been some months since you've last posted on this, but let me ask though, for ordering purposes... What socket is this specified as? Cheers, Bryan
