Will a Pentium G620 bottleneck GTS 450/GTX 460?

post #1 of 6
Thread Starter 
I might get this processor and an H61 mobo for a cheap build to hold out for a couple years until I graduate from school. I know it has Intel HD Graphics 2000, which is more than enough for all my word/excel/pp stuff, but I want to have a dedicated video card for some occasional gaming like BFBC2. I really want the GTX 460 1GB, but if it is going to be bottlenecking it a lot, then I might as well get a GTS 450, if that doesn't get bottlenecked. The resolution I am playing on is currently 1600 x 900, considering an upgrade to 1920 x 1080. No plans for overclocking.

This is the processor you're talking about I assume http://ark.intel.com/Product.aspx?id=53480

At those resolutions the game would struggle to run on a 2.6ghz dual core, even high quality sound in that game uses quite a bit of cpu cycles.

BF:BC2 is a true quad core game, meaning it can potentially max every core in a quad core.

A 460 would be sufficient for the game though, I'd avoid the 450. The 460 is about to have a price drop as the 560 NON Ti version is about to takes it's place price-wise.

But it sounds like what you're getting are gifts and you don't have a decision on what you get CPU/Mobo wise, or are you able to chose ?

Yes, I am choosing parts for a desktop since I cannot play games on my laptop. I'm only worried that the GTX 460 won't run at it's full potential because of being held back by the processor. Also, the GTS 450 isn't that bad, as it plays BC2 maxed out without AA very smoothly with an AMD dual core (from the videos I've seen on YouTube).

I like the Pentium Sandy Bridge because it is very cheap, low power, and L3 cache, unlike the Athlon.

This is relative to what you personally find acceptable performance to be. At that resolution you're correct in assuming the 460 would be bottlenecked by the processor, though you could easily lower settings to make up for it, but, the logic of it will still be that the 460 wouldn't be able to reach it's potential.

L3 Cache means more for other software, it's not important for gaming. All of the Athlon II/Phenom II's when compared didn't show a discernible difference in gaming with or without a L3 cache. The Intel Sandy Bridge procs might be an entirely different story, but, they're also clocked significantly higher.

If your primary game is BC2 youll be better off with an AMD quad core for just a little more.

Your CPU's capability (and hence the FPS at which it starts to hamper performance) in each game is going to be the same regardless of which card you get, keep that in mind.

Comparing a 450 vs. 460 with that proc, the worst case scenario is that you get the same FPS w/both cards, however, with the 460, you can get that framerate w/noticeably higher IQ settings. And that would be very rare occasion, most of the time you'd get higher IQ settings + higher FPS.

And any card (esp. a single card setup) can be brought up to it's 'potential', even with quite a weak chip, (except on a select few, high CPU/low GPU intensive games), you just have to set the IQ settings high enough that the GPU is struggling more than the CPU, and then you get the benefits of the faster card.

A BN would have to be pretty extreme to legitimately justify downgrading your card just on account of that.
