rtcvb32: My card comes up as a Raedon 6900, probably a $300 card while i paid $120 for it.

If you don't need all the highest effects, i'd say go for a card on heavy discount...

Course it really depends on what you plan on playing...

Hawk52: I'm looking to upgrade my Desktop. I'm on an AMD Phenom x4 620 and Radeon HD 4670, which is pretty low end these days. I was eyeing a GTX 760 or a Radeon 270...but I'm trying to figure out how badly they'll be bottle necked by the CPU.

MaximumBunny: Eh? Neither should bottleneck it. They're not very high end cards at all.

But you should be looking at a 280/x or 285 instead of the 270/760 if you're in the $200 range. It's worth the difference. Acheap 960 with the Witcher 3 is fine too on the other end (though something about underperforming against a 280).

Hawk52: So my processor wouldn't noticeably bottleneck a GTX 960? My worry is I'd buy a 200 dollar GPU but only get the same performance that I'd get out of one for 100 dollars. Sorry if I sound dumb, but I'm finding this confusing. :(

MaximumBunny: Correct. The biggest issue would be the speed you're running it at and not the model of processor it is. If you had a decent/$20 aftermarket cooler and bumped it to 3-3.1ghz you'd be doing fine for the latest games I'm sure. That's the only thing I'd recommend if it was my own rig.

Also, if your budget permitted it would you have gone higher? Without the concern of a bottleneck.

Hawk52: Not really. A GTX 960 for 189 is pushing it already. I just got to thinking and looking up things and got scared that I'd be wasting my money on the card. If I had more, I'd just do the CPU at the same time but I don't. :(

ET3D: I assume that your CPU is an Athlon X4 620, not Phenom X4 620, right? I couldn't find any info about a Phenom X4 620.

Your CPU will be a bottleneck, but on a higher end graphics card you can always use a higher resolution, antialiasing or more effects, so the power isn't wasted (unless you go with a very high end card, which you won't). I'd also recommend a higher end card so that if you do decide to upgrade the CPU it won't immediately become a bottleneck. You should still be able to play The Witcher 2 on your CPU at 30+ FPS and maybe GTA 5 at around 30 FPS (although your CPU is around the minimum, and it probably won't sustain a constant 30+ FPS).

I think that in this case just upgrading the graphics card to something good will give you some breathing room. If you have an AM3 board you should be able to upgrade to an FX-6300 (or better in the future, and that would reduce that bottleneck considerably.

Hawk52: Thanks. I went ahead and ordered the GTX 960. I'll aim to upgrade the CPU as soon as I can, whenever that is. My main fear was overpaying for what I would be getting in terms of performance for the old girl.

Rievier: Just curious, how many watts does your power source has?

Hawk52: 600. I made sure to look into that to make sure I cleared the minimum's.
