Will a pentium g620 bottleneck a gtx 550ti?

No, I doubt it'll be a bottleneck.
Sandy Bridge architecture is still pretty powerful.

I heard Pentium CPUs tend to cause stuttering a lot though.

As for Metro 2033, the 550 Ti doesn't have enough power for high-ultra settings @ 1920x1080.

Medium settings is possible, but I think you'll need to turn on PhysX to get decent performance.

Also, no need to buy 1600 MHz memory. That processor won't support that speed.

The processor doesn't choose memory frequency though, the motherboard does. The ones listed in the processor specs are only what they tested it with.

Though I agree, if this is a budget build, don't bother. If you want, you can just buy another 4gb RAM @ 1333MHz and run it in dual-channel with your current one.

Unless of course, the one you have is actually a 2x2gb RAM kit?

Id go with 1600mhz. Because its what? about the same price and works like 1333mhz if the mobo/cpu doesn't support 1600mhz. If he upgrades his mobo or cpu he can use the same ran and run it at 1600mhz.

blake, I agree. but from my understanding he's buying an already built PC, and replacing the 1333 MHz RAM. and excella, that's incredibly possible. I guess I don't know what I'm talking about. Doesn't it just throttle it down? I've got a G860 and I'm pretty sure my 1600MHz RAM is running at 1333 MHz.

I also have a G860 running at only 1333mhz. But when i throw in a 3470 sooner or later, its gonna run at 1600mhz  

Right. Same here. That's exactly what I plan on doing, and that makes sense. In which case I stand by what I said earlier. There's no need for him to replace the RAM he's got at the moment. If he upgrades the CPU in the future, upgrade the RAM with it.

Go into the BIOS, and set RAM profile to XMP.

you dont have to upgrade cpu to be able to upgrade RAM.
hes motherboard perfectly takes 1600 ram so if he wants to do it he can go ahead and do it  

Thanks for quoting me and then telling the OP exactly what i was trying to tell him. And you are sadly wrong that NO, he cannot run 1600mhz ram if the CPU only supports 1333mhz. The ram will work just fine, it will just be underclocked to 1333mhz.

^ No.

I will reiterate:
"The processor doesn't choose memory frequency though, the motherboard does. The ones listed in the processor specs are only what they tested it with."

If what you're saying is true, then we wouldn't be seeing any RAM running at 1866, 2100, 2133, 2400MHz being sold in stores or manufactured.

If the computer doesn't configure the RAM to the advertised specifications if you plug it in, all you need to do is go into the BIOS and either set the timings manually, or set memory profile to XMP(if you're on an Intel system).

I don't know if your quoting me... but i never said that. You guys are getting all picky about everything being said. THE 1600MHZ RAM CAN BE HAD FOR THE SAME PRICE, BUT IF YOU ALREADY HAVE 1333MHZ RAM, NO NEED TO UPGRADE. Sorry for the caps, but come on people.

I was replying to this:

Obviously if he has a cheap motherboard, it ill run at the cpu's default.

No offense, but now you're just being irrational.
Even high-end motherboards have a chance to do that.

And like I said, I was replying to that seemingly definite statement of yours that "he cannot run 1600MHz" 'cause of the CPU limitation.

I don't like arguing. Chances are, his 1600mhz ram WILL run at 1333mhz. I don't think there is any reason to continue the argument.
