Hey everybody,

I just recently got back into simming and I run FSX, however with a bunch of addons installed I am noticing that my FPS is not doing too well and it is getting annoying!
Here is my system specs:

> Mainboard : Asus P7P55D DELUXE
> Chipset : Intel P55
> Processor : Intel Core i5 750 @ 2666MHz
> Physical Memory : 4096MB (2 x 2048 DDR3-SDRAM )
> Video Card : ATI Radeon HD 5800 Series
> Hard Disk : Western Digital WD7501AALS-00J7B0 ATA Device (750GB)
> Operating System : Windows 7 Ultimate Professional Media Center 6.01.7601 Service Pack 1 (64-bit)

Based on my current build, which component of my computer do I need to upgrade in order to maximize my gaming and simming experience? Is my GPU (ATI Radeon HD 5870) being bottlenecked by my PSU or CPU?

Thanks guys!
