Gainward NVIDIA GeForce GTX 650 in PCI-E 16 ver 1.0

[shijilt]

If I add a "Gainward NVIDIA GeForce GTX 650 1 GB GDDR5 Graphics Card" in an "asrock NVIDIA N68C-GS FX motherboard (which has PCI E ver 1.00) is it gonna bottle neck it ?

Processor: AMD FX 6300
4 GB X 2 Corsair RAM 1600Mhz

Now PC is running in onboard graphics.
Upgrade is for Gaming (Mainly GTA series) @ HD (720p) resolution (not Full HD 1080p)

I just did some checking... even though PCIE 3.0 is backwards compatible with 1.1 & 1.0.. issues have come up... mostly because of the lowered power on the motherboard's slot itself. A few years ago I had an issue with an older Asus motherboard that should have worked with a 6850 card.. but just wouldn't. Even the manufacturer was stumped.. but it did work with the NVidia 8850GTS-512 that I had inside it.

According to some other users the GTX 650 seems to work ok in older motherboards. I'll link you to what I found:
