My son and I have been upgrading his PC repeatedly over the last few years (on the cheap). He is a PC Gamer and we take tips from the largest magazine in that genre published in the UK. They have current recommendations on the best "value for money" upgrade components and the Sapphire 11180-00-20R HD6850 1GB GDDR5 Graphics Card was their recent suggestion when the time came last month. My 15 year old did the whole swap out of the old for new himself; with the ease we all hope for. No software issues with our old bullet proof XP operating system, though it works with all later versions as well. And the grapics? Wow! Keeping in mind the reasonable price (Dad does not allow upgrades that generally exceed $100 per pop) it is astounding. Note on the picture that it does take up the space of two slots at the back of the machine side by side. It only uses one card slot, but there is the potential that it could cover another, blocking that out. We had two slots available for an older PCI technology, so we opted for that kind of connection as there was nothing else to conflict with in those slots. As the online PC games get more detailed and awesome, there was hesitation in the graphics. That is a thing of the past and the games have actually picked up speed and are so much smoother and at the pace they were intended. That was a big surprise to us...we knew there was hesitation, but we did not realize the pace of the game was being compromised. There has not been a single graphics quality or hardware issue in the past month since installation. My son and I say skip the super duper 500 quid graphics cards if you don't have money to burn, but do spend what it takes for this card and get a great return on your investment.
