I have recently purchased a 6870 and I have the Intel Quad q9650 running at 3.5GHz, my friend told me that this cpu is an old technology compared to my Video Card and I have to buy an i7 to get full potential of my 6870, do I really have to change it? (which means that I will have to buy a Sandy Bridge 2600k with mobo) or is it OK to keep it with the 6870 for the next 1-2 years or so.
Will my CPU really bottleneck my Graphics Card?
My friend confused me
Your friend doesn't know what he is talking about
There will not be a bottleneck, and if there is, it will probably be barely noticeable. I used to have an HD 6970 with a Phenom II At 3.2GHz. It ran my games great and without any issues. Your setup has a better CPU than mine and a good GPU. You should have no issue.
+1 to all the above. you dont need a high end cpu like a 2500/2600k until you really get into the high end gfx cards. you will see improvement, but not enough to justify buying one unless you have money to throw away.
9550 is way more than enough for that card. At 3.5 it's more than enough for two. I wouldn't look at upgrading it for the same 1-2 years you wanted out of that card.
*** im keeping my Q6600 nothing more is needed except more GPU.
