Okay, so i am PLANING to buy a Nvidia Geforce GTX 550 Ti 1GB but im not sure if my motherboard has a PCI-E x16 graphic slot (yeah im kinda still new at this stuff) so here is a picture of the motherboard



Here are the rest of my PC specs:

Operating system: WINDOWS 7 32-bit
RAM                      : 2.1GB
Processor             : Intel Core 2 Duo E7500 2.93GHz (Wolfdale)
Memory Type        : DDR2 2048 mbytes
Power Supply        : FPS 500w

If im not MISTAKEN i have a LENOVO m58e  computer

so is my pc compatible?What do the Lenovo specs say for your model?

Various PCI slots. From top to bottom:

    PCI Express ×4
    PCI Express ×16
    PCI Express ×1
    PCI Express ×16
    Conventional PCI (32-bit)
Your motherboard physically has the PCI-e 16x slot, however card/cooler height will be your influential factor given that this is not a normal board layout. as long as the card does not require 2 I/O shield slots then you will be fine.

Example of dual slot


Single slot.

what do you mean by 2 I/O slots ? you mean like the first picture you posted?
