Need Help Getting a new GPU!

[arnellagen]

Hello guys.. So i've decided to upgrade my gpu just to save some money (Gonna build another pc once I go to college)
So here are my specs http://prntscr.com/3yigtw
Cards that are in my mind are :
1. GTX750 Zotac Version (no Ti)
2. HD7750
3. R7 250
4. GTS450
All these are at around the same price on my homeland which I'm visiting..
Since I'm upgrading from 9800gt Which of these cards WONT work on my rig? And how do I know what's my PCIe version?
Thanks a lot in advance!!!

I would get a GTX 750.

The GTX 750 is your best choice. Don't expect a huge performance improvement over the 9800gt. But you will get a good 30-40% gain, 1gb of GDDR5 memory, and dx11 for new games.

I also have a sandy bridge processor (i3) and my (cheap) motherboard is PCIe rev 2. It is likely that yours also supports at least PCIe rev 2. All of the cards you listed are compatible with rev 2 and 3.
I am running a GTX 660 on mine and it games very well.

GTX450 and R7-250 may need more power. How strong is your psu?
GTX750 needs no extra power; I would pick that.
pcie 1/2/3 are all forward and backwards compatible with no performance difference. A Moot point.
Your motherboard spec should say.

Yep. As long as you have PCIe 1.0 x16, PCIe 2.0 x8, or PCIe 3.0 x4 or above, you are fine. Even PCIe 1.0 x8, PCIe 2.0 x8, or PCIe 3.0 x2 wouldn't probably bottleneck with that GPU.

Agreed, go with the Zotac GTX 750 http://www.amazon.com/gp/product/B00IFYTNQ0. It will give you the best performance for the money and also consumes the least amount of power.

Yep.
