G530+GTX 460=Bottleneck?

[Hkcuong]

I'm using the G530 CPU and I intend to upgrade the VGA to GTX 460. I've asked for opinions from other forums and they said that it could be a huge bottleneck when combining them. They said that the highest GPU for me is the GTS 450. What do you think? Please show me some suggestions.
My full spec is
GA-H61M-S2PV (rev 2.0)
CPU G530
GPU: ASUS nVidia GTS 450 GDDR3
2x2 GB 1333 KingMax Memory
Acbel 550W CE2

I would think you are going to get a lot of CPU bottleneck.

tomshardware did some tests with a G530 and a GTX 560 Ti

so the bottleneck is game dependent, in some games I think the G530 could bottleneck a 9800GT (let's say SC2 in low/medium settings and res with a lot of action), but in others it would be more than enough even for a GTX 680 (let's say metro 2033 with 3 screens),

the GTS 450 with DDR3 (regular cards use DDR5) is probably not a great card for high res/settings, so if you can find a GTX 460 for a good price, go for it... some games will run faster, and in others you at least can use higher detail settings keeping the same framerate.
