Coming to AMD territory? - Page 6

post #51 of 55
The 570gtx will get you more FPS in some games, while the 6970 will get you more FPS in others. It really comes down to what games you play. It appears the 570gtx outperforms the 6970 in BF3, so if that's your game then Nvidia would be a better choice. The other nice thing about Nivida cards is Physx. If you have an ATI card your going to compute Physx through your CPU, which at the moment isn't coded very well. Hopefully in the future Physx coding will prefer a CPU.

Most 570gtx's are excellent overclockers. I see a lot of people running their cards @ 900/2000. At those frequencies the 570gtx will give you the same FPS as a 580gtx.

GTX 570: 152 GB/s
GTX 580: 192.4 GB/s

Of all of these, I would say the 570 is the only card that begins to show memory bandwidth restrictions when the core is overclocked beyond 850MHz and even then it's not that obvious. Overclocking the memory as well compensates for it, naturally.
Im talking about memory interface...The Fact that the 6950/6970 are 256-bit versus 320-bit and 380-bit for the 570/580....I've heard that has an impact on overclocking potential, but that could be wrong...

Now it came just to these two... Asus GTX 560ti TOP and ASUS AMD Radeon HD6950... They are both close to performance of their older brothers, and they are priced the same, 220 euros... So it is just matter of nVidia, AMD thing...

The next week me and my friend traded for a GTS 450 and flashing stopped, Nvidia control panel was easily figured out, and I OC'd that thing to a GHz. That is why I choose Nvidia.
Okay when you bought your card yes the drivers were horrible and buggy but since then they have corrected all of that. Not to mention the new CCC is pretty snazy. Not only are the 5770's great overclockers they were cheap and scaled well in CF. I still have two CF'd 5770's both run an overclock 1000/core 1400/mem. I understand not all are equal but you can't just lay a blanket statement that yours sucked so all Radeons suck. You can not base a whole brand of cards based on your experience. I have owned both Nvidia and AMD and both have strengths and weaknesses. I am currently running both in my rig right now AMD for rendering and Nvidia for physx.

@OP If you want physx without having to buy two cards go with Nvidia. If you want similar performance with the ability for multi monitors then go with the Radeon. In all honesty you probably won't notice a huge difference in either card 570/6970 because most of the tests I have seen are only about 5%-12% difference in different games.

In the old days ATI and eventually AMD had really buggy drivers but that hasn't beent the case as of late. It also used to be that Nvidia ran really hot and were power hungry but as of late that is not the case. In fact the 570(from the tests I have seen) actually uses less power. If it helps though If you are more familiar with Nvidia stay with them. You will not be gaining much if anything by switching from Nvidia at this time.

@Rawfood As I understand it that doesn't have a lot of impact on the actual overclocking just the actual bandwidth you can theroretically get out of the chips themselves. It's like taking the ocean and pushing through a small canal. No matter how much you push you can only get so much flow and at some point you reach the diminishing returns. Thats where the more you push the less you get.

So I have talked with my parents, because of the prices and thing like that... Good news is that they are gonna help me to buy the one I want. The thing is, I have more confidence in nVidia and I am really familiar with them, I mean I have used them for about 6-7 years and didn't have anysingle problem... But I can se that AMD/ATI now is totally different thing than few years ago, their prices and performances are incredible... So I can go with ASUS RADEON HD6950 for 239€ or MSI GTX 570 for 299€... The reason I am affraid to go with AMD is that I don't know how will they performe in some games with Physx or bigger tesselation... I read on sam review sites that nVidia GTX570 had better score in some more important real-time benchmarks (hawx2 for ex.) So maybe grass will stay GREENER on my side, maybe gap between AMD and nVidia isn't big enough for me to jump onto other side... I will have those 300€ until the end of February, and then we will se what will Kepler and Southern Islands give us...?
