GTX 750 TI bottlenecked by the old hardware?

[Taias]

Hello, everyone!

I am looking to buy a new GTX 750 TI alongside with a new PSU Corsair VS450.

My current CPU is Phenom II x2 545.

My question is: will my new graphics card be bottlenecked by the old CPU and is the PSU I am looking into buying sufficient for the GTX?

Thank you in advance.

I dont think it would bottleneck it a ridiculous amount but the Phenom is pretty old, especially if it's the dual core variant. And the GTX 750Ti isn't that power hungry so you might barely suffice. I'd upgrade my PSU to maybe a 500W from a trusty brand just for safety reasons. Better to be safe than sorry.

What GPU are you using now? It may not be much of an upgrade to bump to a 750Ti. The cheaper R7 265 actually performs better in most cases. The R9 270 might be a better bet, with that PSU.

It will be a bottleneck yes, for about 20-25%. And that PSU is fine if you are buying gtx 750ti that does not require 6-pin connector, because some models of gtx 750ti does require additional 6-pin connector (ASUS DCU, EVGA FTW, GIGABYTE WF2). Good models of gtx 750ti that does not require 6-pin:
Msi gtx 750ti TF, Palit stormx dual gtx 750ti oc, Gainward gtx 750ti GS.

Your answers are somewhat reassuring

AMD Radeon 4650 is what I currently have. I went with GTX over R7 265 or R9 270 due to its slightly lower cost. As I am running on a tight budget, I think getting the AMD one would require a better PSU, which would be over my budget scope.

I am hoping to buy a new CPU in foreseeable future.
Is there any you recommend as a good replacement (under 150$)?


I was also curious about how to unlock the 2 remaining cores and how much does it effect the system in general. Is it really worth doing it?

Thank you all for your responses.

If every retail site has them written down as dual cores including AMD, they're probably unlockable (unless you take em to AMD and prepare to do some feet kissing).

Where are you shopping from? The 750Ti appears to be the same price, or in some cases, more money than the AMD R7 265. The R7 265 also beats the 750Ti in most benchmarks.

True, you'd need a PCI-E connector. I didn't realize that PSU was missing one. The Antec VP-450 comes with one, for $37 on Amazon.

The R9 270 should also be fine from a total W standpoint. A R9 270 with that setup would require 350W minimum, and 450W would be fine. (http://www.extreme.outervision.com/PSUEngine) Only $10-20 more, and adds a significant boost. Here's some good comparisons:

IMHO, the 750Ti is a solid card, but should be reserved for cases with restricted upgrade options.

Kind of hard to find a non-used AM3 CPU these days. If you find one, you could bump up to a AMD Phenom II X4 Black Edition 975, and possibly OC it a bit. Personally, I don't think you want to spend $150 on a socket that's been dead for 4 years.

One alternative would be a $69 Intel Pentium G3258 Anniversary Edition, along with a nice Z97 mobo, like the Gigabyte GA-Z97-HD3. Not only would that get you the latest generation dual-core, but it would put you on a platform that could take a latest gen, (and possibly next gen) i5 or i7 down the road. Plus it could be overclocked pretty hard.
