Just guessing that the CPU will be a little stronger than the GPU but if there is a bottleneck, it won't be noticeable. BTW, the EVGA GT240 is poor value for the price - $100!?
Spend $15 more and get this:

XFX HD-477A-YDFC Radeon HD 4770 512MB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card - Retail
It will run circles around the GT240. Believe me, it's worth the extra $15. Wthat's $15 anyway? Forego that large pepperoni pizza and pitcher of beer once and throw the cash you save into your next videocard.
