I was looking to change my GPU to a 750TI. I have a pentium D925. I wanted ti know will this bottleneck the 750TI.
I have a very old PC. So if i have to change the CPU, ill have to change the motherboard, and then the RAM sticks too has they are of old memory.

Hence, if a pentium D925 will bottleneck a 750TI, whats the best CPU to get for a LGA 775 socket?
Thank you!

Seems like it will bottleneck significantly. There's a thread similar to this which talks about Pentium D 820 paired with a GTX 550 Ti, which is of course, noticably slower than the 750 Ti.

If you're going to change the CPU, RAM, and motherboard, it might be fun to try out that new Pentium G3258 Anneversary Edition (if you're on a budget). It's been overclocking really well according to reviews.

What pbm86 is referring to is the fact that LGA 775 was supported by a lot of different chipsets over many years and over many generations of processors. A Core 2 Quad might not necessarily be supported by a board which came with a Pentium 4. You'll have to check your motherboard, find out what chipset it is, and look for the list of which processors are compatible with that chipset. If the fastest CPU you can get does not offer a significant boost over your current one or costs too much, then you should consider getting a new motherboard platform.

Here are te details of the MoBo.
Manufacturer-Lenovo
Model-Lenovo LGA775
Version-Thinkcentre A55
Chipset vendor-Intel
Chipset model-946PL/GZ
Chipset revision-C1
South bridge vendor-Intel
Southbridge model- 82801GB(ICH7/R)
South bridge revision-A1

So could you tell me he best CPU for this chipset? And would it provide a boost over the D925? And not bottleneck a 750TI?

Thank you!

Looks like you're in luck. There is a worthy upgrade. A lot of people have asked about the same situation as you. Some are even talking about the exact same computer model.

The fastest CPU you can get, according to this chart, is the Core 2 Duo E4700:

http://www.cpu-upgrade.com/mb-Intel_(chipsets)/946PL_Express.html

A CPU's performance is based on a lot more than the cache size and clock speed, so some of the other CPUs like the Pentium 4's may look faster, but they're not. Just know that the list of Core 2 Duos present are the fastest group of CPUs compatible. I wouldn't buy anything but the fastest Core 2 Duo, the E4700. A quick search yields a market with various prices; from the original $200 price to $70 for four of them. It's a CPU, so it's very hard to make a counterfeit one that works, but be careful about who you buy one from.

Yes, there are faster Core 2 Duos, but your motherboard's 800 MHz front side bus is limiting your options. I believe that the fastest models under the Core 2 moniker used 1066 MHz or 1333 MHz FSBs. Don't plug in those models.

How fast is this CPU compared to your current Pentium D 925? Other threads say significantly:
http://www.tomshardware.com/forum/258945-28-pentium-core-e4700

It possesses the newest architecture there. Compared to your Pentium D, it uses substantially less power and consequently runs cooler.

If you're talking specs, they look almost the same, but the 2 Duo has much better scores on benchmarks:

I don't know how much the thing will bottleneck the 750 Ti (looks like it still will, sorry), but it should be MUCH less than your Pentium. It's something you have to risk and try out. Perhaps you should try overclocking the CPU? Good luck!

I would just save up and replace the whole system but using a 750Ti with your current system is not a good idea so be advised that it may cause more problems that it is worth. Stock psu is likely too weak and the airflow through the case is likely too poor.

Maybe so, but that's what makes the 750 Ti so unique and fit for this situation. Uses only 60W vs over around 100W+ for comparable GPUs. It's the most power-efficient card relative to performance on the market. Therefore, the PSU should be able to take it. On top of that, if he switches out his Pentium for the Core 2 Duo like he asked about, he's reducing his CPU power requirements from 95W to 65W, all while improving performance. Only 30W more total on the power supply? Almost certainly not a problem.

Yes, consumer cases are almost always crummy on airflow, but the 750 Ti shouldn't cause a thermal problem. Again, the Core 2 Duo that he might buy produces less heat, giving more leeway for the GPU. Of course though, if there is any place for a fan in there that isn't occupied, mount one there.

But yes, ultimately ABHIonPC, you want to replace your system sooner or later. It's just a matter of whether if you want to spend some now, then spend more later, or if you can take the wait and save money on messing with this intermediate solution.

I can't be sure since I don't have your system, but it should be at least playable on medium.

This is fine. If I were to recommend one that wouldn't be bottlenecked, it'd be a super-out-of date one that would be weaker. It's not a good idea to get old hardware for a GPU.

If you have the tower ThinkCenter, what video card you can use would depend on the power supply. I would say a regular 750 would work well for you. I would not worry too much about what can match your system now as you can always move the video card to a newer system. A model like yours but with a newer Core 2 Duo CPU should be about $100-120 used. Basically for $200 you can have a much faster system with a video card.
