Im not so technical and im still in the process of learning. I am having trouble with this compatibility issues.

My current rig:
Processor: i3 530 @ 2.93ghz
Ram: 8gb
Video Card: Palit GTS 450
Motherboard: gigabyte h55ms2h
PSU: HEC 500 watts (RAPTOR)


I was planning to upgrade again my pc. and i would start to buy a new graphics card. Seems i can't find GTX 660 cards this day. then 1 offers the TI version of it. Asus GTX 660 Ti DC2, TOP 2gb/192bit

Can my current rig can handle this card? thanks in advance. Please help me.

It should be able to handle it OK.
Make sure that your PSU has the proper 6pin or 8pin headers for the GPU, but wattage wise it seems to be adequate. Going to be a big step up from the GTS450 lol

You will notice some bottlenecking in CPU-intensive tasks such as new games.

True, games like skyrim and other CPU heavy games will not see full potential of this card, but it will still run much better than with a GTS450, and most games are not all that CPU heavy.

Still, with next gen console ports coming out soon you may want to start saving your pennies for a decent platform upgrade (CPU, Mobo, Ram) in a year or so if you want to continue playing newer titles.

that was fast, thanks guys. Thanks for all the answer. My current PSU has a 2 6pin. I just want to start on the card. then the rest upgrade will do. thanks again. I am planning to upgrade because my current rig is already 4years old :lol:

Think of it like plumbing. You have a certain amount of water (performance), and as it goes through various points in the tube (hardware parts) then it can impeed that water flow. An ideal computer is one that is well balanced and has no bottlenecks. This means that no single part is going to prevent other parts from achieving their maximum performance. The bigger your pipes the faster the water flows, but if a single section of piping is small, then it restricts the water flow in all parts after it.

As an example, my computer was built for video editing and games. When I first built it I could not afford a SSD system drive, or new HDDs, so I had all new hardware but was running the OS on a 5 year old 500GB HDD. It was no faster at booting up or rendering projects than my Core2Duo system that I had upgraded from simply because the HDD could not feed information to the rest of the system fast enough. So for program loading, and rendering my HDD was a bottleneck.
However, while games had an initial slow load time, the performance in the games was just as good as it is today because once the information was loaded into system memory (RAM) then it took the HDD out of the equation and so it was not a bottleneck for that kind of workload.

A current example is that now that my computer has plenty of ram, fast SSDs and HDDs, a good CPU and GPU I have a bottleneck in the amount of vRAM installed on my GPU. My GPU is plenty fast for the games that I play, but because it only has 1.2GB of vRAM it causes large games like Skyrim (especially when modded) to have weird frame rate issues because it is constantly having to clear out and replace information in the GPU's vRAM. So even though most games I play are only using some 30% of my GPU's horsepower, I still have issues because there is not enough ram on the GPU, and the GPU cannot process the information until the information is in the vRAM. So what happens is that the GPU makes a request for information in the vram, the vram realizes that it does not have the information because it is full, so it purges information and makes a request to the system ram. The system ram gives the vram the appropriate information, and once loaded the vram gives the information to the GPU. Then the GPU asks for the next bit of information... which the vram just purged to make space for the last bit of information, and round and round it goes causing all sorts of dropped frames and studdering as it struggles to purge and load information that it needs. But if I had a GPU with (lets just say) 3GB of ram, then it would hopefully be enough space to hold everything at once and cut out a lot of that purge and load process to give a nice smooth experience again. I do not need a faster GPU (though I will probably get one in the process)... just a more capable one.

So in short, a bottleneck is any point of bandwidth or capacity which causes noticeable performance issues for a given workload. Your new GPU is of a class slightly higher than your CPU, and so in some workloads (again Skyrim, because it is a large and difficult game for computers to handle) then your CPU will become a noticeable bottleneck in the system which will prevent you from getting full performance out of your GPU, causing droped frames and other issues while the GPU waits for the CPU to process a certain bit of information.

Thankfully, there is a unified storage called ReRAM which is on the (distant) horison. This will be memory that will be cheap enough to make in bulk, and fast enough to use as RAM. This will open the doorway for unified architecture where you just have one central set of memory rather than storage memory on your HDDs and SSDs, and system memory on the motherboard, and vRAM on the CPU. It means that all programs stored are active; no more load times, no more moving large resources around between devices, much less processing latency, and much simpler computer architecture (though more complicated OS and program design to prevent hardware from fighting each other). When it is ready in the next (hopefully) 7-10 years then it will remove most common bottlenecks in computer systems, and allow for much easier system upgrades and scaling. *sigh* but that is the future, and not today.
