Here are the specs:

ASUS P7P55 pro motherboard
Core i5 750 @ 2.66 GHz
Geforce 9800 GT
Samsung Spinpoint F3 500 GB
4 GB of G.Skill Ripjaw Series DDR3 1600 MHz 9-9-9-24 @ 1.5 volts

In Sins of a Solar Empire I'm dropping frames in some of the larger battles. When I exit the game, I see the CPU usage chart (I downloaded this gadget) has been at almost 100%

Is my i5 not powerful enough to handle this game??? Should I overclock it and how much improvement should I expect???

The i5 should be fine for that game, that doesnt seem to be the source of the problem... monitor size?

Are you one highest settings?

monitor is a 46" samsung 1080p 120 Hz LCD. I'll have to check what the settings are later. This is actually a question I'm asking for my cousin, for whom I just built this system.

My take on Nvidia's cards are theres a wide performance window with the name
9800gt. The 9800gtx+...... the plus, has the same specs as the GTS 250. The regular 9800 does not. 9800gt < 9800gtx<gtx9800+<Gts250<Gtx260<GTX 260 Core 216
Depending on your resolution and expectations your card is not that powerful.

At that resolution you are pushing the limits of a 9800 GT. That's why you get good frame rates until you hit an intense scene. While it is still a decent card, 1680x1050 is about the limit for it to maintain good frame rates throughout most modern games.
