Hi guys, I am looking to upgrade my graphics card this christmas and was looking at moving up to a http://www.amazon.co.uk/Asus-GeForc...1_2?s=computers&ie=UTF8&qid=1356188929&sr=1-2 from a http://www.geforce.com/hardware/desktop-gpus/geforce-gt-440-channel/ My system specs are as follows; Operating system: Windows 7 Home Premium (x64) Service Pack 1 (build 7601) Install Language: English (United States) System Locale: English (United Kingdom) Installed: 21/01/2012 12:18:05 System Model: Hewlett-Packard HP Compaq 8200 Elite CMT PC System Serial Number: CZC14750XR Asset Tag: CZC14750XR Chassis Serial Number: CZC14750XR Enclosure Type: Mini-Tower Processor: 3.40 gigahertz Intel Core i7-2600 256 kilobyte primary memory cache 1024 kilobyte secondary memory cache 8192 kilobyte tertiary memory cache 64-bit ready Multi-core (4 total) Hyper-threaded (8 total) Main Cirucit Board: Board: Hewlett-Packard 1494 Serial Number: CZC14750XR Bus Clock: 100 megahertz BIOS: Hewlett-Packard J01 v02.

I am currently using a GeForce Gt440 card which is quite old and struggles with performance on some games. I am interested in the Asus GeForce 560 TI but have no clue if it will even work in my machine, I looked towards the manual for my pc and it suggested cards worse than I currently have and I want better performance not worse! The manual says that I have 3x Full length PCI slots, 1x PCI Express slot and 2x Full Length PCI Express x16 graphics. The 560 TI has according to amazon "PCI Express & PCI Express 2.0 support" and looking at the specifications of both on their respective websites the GT440 uses PCIE 2.0 x16 and the GT560 TI uses PCIE 2.0. Given that the GT440 is already working in a PCI Express 2.0 slot is it safe to assume the 560 would be compatible?

Thanks in advance.
