I'll be building a new SB rig sometime this year (probably summer).
I have an aging NVIDIA gtx 260 216SP but I want to upgrade to a high end AMD card or possibly a new NVIDIA card.
However I won't get much selling the card!
So I thought it could be put to better use as a dedicated physx card in the new rig.
I'm pretty sure it would work with a newer geforce but how about with an AMD 6xxx for example?
Would it work if I simply installed CCC and the physx drivers?
Or would I need to get an NVIDIA card?
Also, will dx11 work correctly? Even if the gtx 260 only supports dx10?
It can work with an AMD 6xxx, but Nvidia doesn't want you using "enemy" cards so they disable it in drivers. There are hack drivers you can use if you want to use an AMD and PhysX card.
DX11 will still work. That is handled by the GPU so thats all that matters. Realize before you do this that there are only a few PhysX hardware accelerated games out there. If you don't play any of them, then all that GTX260 will be doing is adding to your power bill.
I play a lot of games with physx.
Besides its not going anywhere right?
Only more games will take advantage.
I wanna be sure I can still run physx on max settings down the line.
Sounds like a hassle.
Should I go for an AMD 6950 flashed to 6970?
Or a 560 ti (the gigabyte oc'd versions are fast)
The dedi physx assistance would really help me see smooth framerates with physx on (id think) using these cards.
Id be running the games at 1080 res. What card would allow me to max out crysis at that res (sub $250)
Also couldnt I just downclock the 260 when not in use?
Theres only about 20 games that support this, and most are not worth playing. Batman:AA, Cryostasis, Metro 2033, and Mirrors Edge. There are other games out there, but either suck, or use PhsyX in only one level. If you play a lot of Crysis, L4D2, TF2, or any of the BF or COD games, its only going to do anything other then consume power and emit heat.
Cough Mafia 2 has great game play and is one of the best physx titles out there. The GTX 260 is more or less overkill for physx as a dedicated card however you could try the sli hack (software) to enable sli on non certified Intel boards and on boards using ATI chipsets. I am using this my self with no problems on a ancient 790x board. Sli isn't a bad option for you as getting a second gtx 260 is very easy and cheap. $90 can still get you a lot of power these days on the second hand market.
Sure you can use the software hack to run PhysX with an ATI card in there, but if you don't want to go through that hassle then it's easier to just stick with nVidia cards. No matter what card you use a 260 is overkill for PhysX right now, but at least you know it's not going to slow down your rig when you use PhysX for a long time . Anyway, flashing a 6950 to a 6970 is something you should consider, though I'm guessing by now the 6950s they are shipping are chips with defective sharers and that the original 6950s were perfectly good 6970s they had to shoehorn into a lower price point. Then again that's why they have a backup BIOS ^_^. If not then a GTX 560 or 570
I would have mentioned Mafia 2, but I know many who don't like that game because of how short it is.
The 560 is a fine card. Like with most Nvidia cards AMD sells one similar in performance for less $$$, but your not buying a dud. I'd probably grab an Nvidia card to just to avoid hacks/driver issues. You wouldn't want it working for X months/years only to have new "unhackable" driver come out that prevents you from using it anymore.
Considering how few games can use the GPU for PhysX (and I play none of them.) I would take the 6950. I'd have to double check to see if the games that I do play perform better on the GTX560 or 6950/6970.
They both have their wins and losses.
However this fails to consider that the 560 would be factory overclocked by a lot (800 to 1000mhz core)
Which in toms benchmarks shows a major improvement (near 570 level)
Also assuming nothing has changed the 6950 would be flashed to 70 and probably overclocked a good bit by me.
However nowhere near as much oc as 560 which comes with much better cooling
So let's assume then that this is 570 vs 6970 (probably overstating)
They are so neck and neck I can't say which is better.
Thoughts, on all this, to ease my insanity?
Just looked at a review to see, because I found it odd how the 560 sometimes pulls ahead of a 6950. As far as I can tell it's almost only on titles that Nvidia sponsored. Anyway here's a review and an interesting comparison:
They do recommend it though at the end, due to being a bit cheaper and very close in performance. They note it's biggest issue is the memory bandwidth, and if you overclock the memory it'll become quite a beast.
At what I assume they mean 1680x1050, the GTX580 is barely faster then the 6950. at 1080, its nearly a tie. If you do unlock that 6950 to a 6970, then it will be faster then the GTX560. Seeing as we are talking basically dead heat here (1-4% is nothing we'd be able to feel/notice) I'd still get the GTX560. If you want to use the old 260GTX as a PhysX card it will be easier with the GTX560. If you won't be using PhysX, or care only about which card is faster, get the 6950.
The other thing to consider is that I have a relatively new 550w corsair.
Enough juice to supply stock 560 or 6950.
However, flashing/overclocking the 6950 and overclocking the 560/adding the gtx 260 for physx would probably warrant a new psu.
Im assuming that the extra physx card would need at least a 600w (assuming it never gets near full load).
