Not sure if that's All the information or if more is needed please let me know, and i use the COMPUTER for gaming.You could upgrade to a better CPU pretty cheaply buying a used more powerful Core 2 Duo CPU for the system. The E4400 is on the sluggish side with low clock and low cache. A CPU like the Core 2 Duo E6600 with 2.4Ghz with 4MB Cache would show noticeable performance advantage.

Are there games you want to play on this system that you can list here so we can determine if its even worth investing any money into a CPU upgrade? Core 2 Duo's while able to play many CURRENT game titles, are being pushed to their limits for the most part with many current games that would ACTUALLY run on it. Titles that require a quadcore minimum if able to install and run on a Core 2 Duo Dual-Core system will likely lag badly.

Video card upgrade could be completed too, but the Core 2 Duo system is going to be a bottleneck for the really good video cards and your power supply would probably have to be replaced with a higher wattage supply to power a good gaming video card, however there are some Radeon and GeForce cards that can run powered direct from PCIE slot and the stock power supply and run games on normal or lower than normal settings, or lower resolution to up the frame rate.So i bought the Core 2 Duo E6600 with 2.4Ghz with 4MB Cache, it should be here tomorrow, consider me stupid but, if i'm using a 2.0, and i upgrade to a 2.6, does 0.6ghz really make a difference? What kind of performance am i looking at? and since its dual core, would it be 0.6 x2? so 1.2ghz faster?? Here's a comparison of the two. These numbers are only a broad data throughput average, not a definitive which is better (although not a bad measure of potential):

Sorry you'll have to click on the compare button for each:

https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core2+Duo+E6600+%40+2.40GHz&id=912Benchmark numbers with IS over OF % over 100 equation places the upgrade at 27.057% increase in CPU score at 2.4Ghz. Because it looks to be a Dell, you probably dont have the ability to overclock that 2.4Ghz to 3Ghz or faster as I have seen people push the E6600 with strong overclocks with really good performance for this era of CPU if you can keep it cool.

with 1135 = the E4400 and 1556 = the E6600 CPUQuestion.
What chip set does the motherboard have?
Is it a Dell Latitude E6410 System?
It could make a difference.
