Hello,

If I were to upgrade from 270X to GTX 780 to run games at maxed settings, 1080p and have PhyX to High such as Akrham City, Arkham Origins or Planetside 2, do I really need to buy a another GPU?

A lot of people recommend using 550ti to handle PhysX but my local computer shop only has a 650ti. Do I need to spend that much more money and will it not drag the performance down? Or will the 780 handle PhyX by itself?

Thanks.

considering the current $50 or so price differential get the 290x, in terms of price drops you may be waiting a while with mining, but just keep your eye on it :)

First, the GTX 780 is going to give you a huge performance bonus over the 270x. Since the release of the GTX 580, people haven't really had to rely on dedicated PhysX card.

I say get the 780 and if you determine you aren't getting the framerates you'd like at high detail and high PhysX, then consider getting the dedicated PhysX card. Chances are, you'll find the 780 more than powerful enough on its own.

You won't "need" a dedicated physx card for the current games out there. The 780 is a beast my friend has one and I have a Titan Black, His card performs within 10% of mine in most situations (at 1080p).

Thanks for the answers. But I have not found any benchmarks to see any performance loss for turning PhysX ON or OFF. I want to know if they are major performance loss on 780 with PhyX (if they are any).

EDIT: Also I am preparing my PC for Arkham Knight in 2015. Arkham games are always the spearhead for PhysX demonstrations, I just want to be prepared.

The 290x is an extremely good card for the price, but you'll only really see any improvements over the 780 once you use 1440p or better resolution. It's probably more futureproof but if you're sticking to 1080p then get the 780 :)

Damm, this is getting more difficult than I thought haha. Maybe I should just wait a few months, hopefully prices would go down and may make my decision much easier. $700 I can achieve but a bit too much to be honest. Anyone know what time of the year PC parts usually drop price? Here in Australia its usually in June but bitcoin mining....

EDIT: Currently a typical 290X is $700-800 (in all major retails) in Australia, a 780Ti is $750-$900 (in AU Dollars and in all major retails).

u cant or should not try to futureprof gpu or cpu when buying new parts, its all going to get more difficult to get good fps in games so xtick to a 1080p monitor, get a good silent 780 and dont try to buy something for the future because you cant run the future games as good anyways. most games are cpu dependent so get the devil canyon later this year and go 5ghz on the i5 will help a lot.

By futureproof i think he means he wants a GPU that will last a few years whilst still maintaining performance. a 290x will most games 60fps @ 1440p for a good few years.

I pretty much just want to play any "next-gen" games at 1080p at 60FPS. I recently moved from PS3 to PC from late 2013 (almost one year old) with my FX-8350 and R9 270X. Even though my current PC is more powerful than the PS4, it cannot really play games at 60FPS and Ultra. 30FPS is very doable but playing 30FPS in a first person shooter makes me sick. Lowering graphic quality helps but then....it will be like having a game console again.

I might stick with my FX-8350 for a bit since it is 8 cores and Intel's Devil Canyon might be $700+ and then I also need to buy a new Motherboard if I were to change from AMD to Intel. I am really interested in Nvidia because I am a game developer and Unity is a game engine that is officially sponsored by Nvidia and I like their PhysX technology. But someone said it will perform bad or not work at all without a dedicated card.

Yes I am sticking with my 1080p since I have not really experience a full 1080p and 60FPS in a while. I played a lot of 720p and 30FPS games in the past so I am happy with 1080p, I am new to this and I bought the same old games from my PS3 to my PC (such as Arkham City and Far Cry 3) and I cannot believe how sharp and pretty games are now.

I can hit 1080p but performance is really bad in my current rig. This bothers me so I wanted an upgrade - High-end gaming.

EDIT: The 290 and 780 are only $50 difference. I am not really sure which one is better since the benchmarks comparing these two are mixed. But I am only using a 600W Thermaltake Litepower. A lot of people said this is a bad PSU but apparently it is a 80+ Platinum. Is it OK to run these cards with this PSU?
