Terrible Performance with a GTX 660 Ti?

confirmed... msi 660 Ti twin frozr PE,
Bl2 on ultra with physx on at 1080p is 60-70fps for me

I don't think so... doesn't seem like it... although I did win it in a 2K giveaway for ahem BORDERLANDS 2.
Also, I will post my clock speed once it downloads.

It happens with some cards with nvidia

GPU-Z

I had issue with my brand new 770, bad beta drivers. Try some other drivers maybe?

Umm, Can you use MSI Afterburner so it shows usage % ?

Let's talk overclocking later, let's diagnose first what's making your games fps very low. Because those are not normal to me.

you need a bigger PSU I have about the same specs but a 650TI and 700W PSU also depends on the brand of your GFX card as well as they all have different specs. The one I have of ASUS recommended 650W PSU. I'm running those games stable at max settings with 50-60 FPS

As long as the PSU is running normally, 600W are perfectly fine. (A system with your card in it should peak at about 320W, putting you around the optimal 50% load.)
Low power or a malfunction can lead to the behavior you described, but I don't think it's your case.

I agree on the fact that you should be able to run games smoothly with PhysX ON. I asked about it to know if turning it to off would make the problem go away completely (it would have pointed to a driver problem of some sort).

I think your culprit is the old installation. Since you tell me that you replaced all the HW (without reinstalling, I take), I think it's your best shot to format and start again: it could be a case of really messy registry, with a pinch of drivers conflict. :)

How about you try it.

if you have to ask don't you may fry it if you don't have a good fan. Exp if you don't have a liquid cooler.

Since the 640 has a locked multiplier, I don't know much about overclocking it. However, it seems like this article could be extremely useful. Also, like schalart said, you want to be careful about temps. Get HWMonitor and make sure that under load ( Prime95 might be useful for maxing out the usage ) the processor stays at a reasonable heat level.

They're really nice. They have mildly worse per-core performance than Intel processors, but they get about the same performance in current gen games, and should get even better as games start to utilize more cores (both Watch Dogs and Battlefield 4 are capable of using 8 cores).

I don't actually see what you're talking about in that thread...

you wont get much more. . honestly.

edit like the guy from tom's hardware said you aren't going to get anything from a 660 ti. Your CPu cannot handle the demand it puts on it.

You won't be able to overclock from bios in a prebuilt system. They don't give you any of the options for frequency or voltage control that are needed.

yeah and not with that CPu and MOBO. I don't even think it has SATA 3.
edit: nope it doesn't so he cannot use a SSD.

I feel you require a lesson on SSD's...

A solid state drive replaces the common hard disc drive's spindle in a vacuum sealed container with thousands of serial bus connections, therefore it does not follow the common format of storing information on "segments" or "sectors" of a hard drive (which are what make up the HDD).

In a HDD, these sectors can contain a set amount of information, for example, each sector could hold 126MB and there could be 2000 sectors. each sector can only contain information from a single file, therefore a file of size 1kb would take up a whole 126MB sector (this is why when you go to right-click properties it has two file sizes, the theoretical size and the "size on disc" or actual storage requirements). If a program uses a large amount of separate files, the game will be slow to load as it has to draw information from more sectors. This is also determined by the rpm (revolutions per minute) of the drive. a lower rpm drive will find each individual sector at a slower rate, therefore a 5400rpm drive with larger sectors is slower than a 7200rpm drive with smaller sectors, even though, smaller sectors would increase the amount of time it takes to load due to having to load more sectors, (therefore, more processing power from the CPU is used).

however, due to the SSD's serial BUS system (similar to a USB device however with more connection), it does not have the restriction of setting data to specific sectors, therefore it is able to load it all from essentially 1 sector and does not have to look to find out in which sector the information is kept in (this is also why you do not have to defragment a solid state drive as the defragmentation process is simply moving sectors to more convenient locations to draw information for use, therefore increasing the performance).

Overclock? But honestly the motherboard in those hp machines is usually terrible so I don't recommend it.

You can try overclocking it, but it won't make that much of a difference. Until you can get a new one, you'll just have to deal with the bad FPS or play older/indie games. That's why CPU bottlenecks are so much worse than GPU bottlenecks : /

High temps are usually a problem from the user's side not the hardware itself.

Alright then. UPDATE: http://pcpartpicker.com/p/1Wwyb

I need to it be under 660 dollars.

Here's my modified version. Even with a mouse, you're still well under $660.

I have a modified prebuilt, so Win 7 came with my hard drive, not as a disc, but preinstalled.

8 CAS Latency for $55. Not bad.

OP would probably be much better off with a higher quality motherboard. It doesn't have to be a $200 RoG mobo or anything, but it should at least have good VRM cooling and 2 PCI-e slots.

That's a pretty nice mobo.
