Today we are going to be looking at an add-in-board partners version of the NVIDIA GeForce GTX 560 video card that might be worth your hard earned money. The card we are looking at today is made by Gigabyte and has the GPU core clock and shaders factory overclocked, so you get an extra performance boost without having to get your hands dirty with overclocking utilities and software. The Gigabyte GeForce GTX 560 OC comes clocked at 830 MHz core, 1660 MHz shaders and 4008 MHz on the GDDR5 memory ICs. The NVIDIA reference design for the GeForce GTX 560 video card is 810 MHz core, 1620 MHz shaders and 4008 MHz memory. As you can see, Gigabyte left the memory clocks alone, but increased the core clock by 20MHz and the shader clock by 40MHz. This is a mild overclock when you step back and look at it, but Gigabyte isn't charging any extra for this overclock as it is their entry level NVIDIA GeForce GTX 560 card design! In fact, this video card is the least expensive of the 14 GeForce GTX 560 video cards that are being sold right now on Newegg.com! So, how much is the card? The GIGABYTE GeForce GTX 560 OC GV-N56GOC-1GI video card is $169.99 after a $20 mail-in rebate!
