Help with video card selection

[Evilball]

Hi all, well I'm about to buy/build a new computer and i was wondering what video card i should get.
here are the current specs of the system I'm going to purchase soon.

MSI 870-G45 AM3 AMD 770 ATX AMD Motherboard
Rosewill Stallion Series RD500-2DB 500W ATX12V Power Supply
PNY Optima 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model MD4096KD3-1333
AMD Athlon II X3 450 Rana 3.2GHz Socket AM3 95W Triple-Core Desktop Processor ADX450WFGMBOX

it's a bit of a budget build, so i'm thinking of around $130 for a card.

been looking at
EVGA 01G-P3-1450-TR GeForce GTS 450 (Fermi) 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
- newegg.com/Product/Product.aspx?Item=N82E16814130572

but was wondering what others thought. and if u want to change anything with my build feel free. I'm hoping to stay under $400 for my total build amount.
i play at 1600x900, i believe.

thanks.

SAPPHIRE ATI 5770 $139.99
EVGA Superclocked GTS 450 $139.99

are both fine choices for the build you're doing

You might want to invest on better quality PSU.

E: Also the mobo is using old 770 chipset and by MSI's site it doesn't even officially support the processor you've chosen.
