Hey,

Kinda a newb with older parts and amd parts... I have an computer with an AMD Athlon II x2 250 3.0ghz... Seems it has no dedicated graphics card. Its running on an integrated AMD 760g.

I am wondering if i can just plug an AMD 7870 in it, or a lesser card... Or will i have to put a new cpu in aswell.

The GTX 660 is MUCH faster- they usually cost more than a 650 Ti though. The other thing to look out for is a deal on one of the higher GTX 500 serises cards (the GTX 560ti and 570 are both great performing cards).

Well, it depends on a few things, what kind of games are you hoping to play? if you are not playing very demanding games you should be ok. Your cpu is going to limit which card you can put in there. your cpu would bottle neck a 7870
And i doubt the stock power supply you have would handle very much. Can you please tell u s the powersupply in your system.

I have an 400w power supply. I am wanting to play semi demanding games at and avg of 50+ fps a sec... Just wondering if i can make an quick fix. If not i will prob scrap the comp and build a new one.

For the 7870 you will need at least a 500W power supply. If instead you would like to have another computer it won't necessarily cost $1200. What would be your budget for upgrading the current machine or building/buying another?
 



Hi Corbin, if your Mobo is based on the 760g chipset then it must be an AM3 board and so will support one of AMD's quad and possibly hex core cpus from the Phenom II range. First thing to do is identify the motherboard make and model (best way to do this is open up the case, there should be a model number in bold somewhere near the CPU). Go to the manufacturers website and look up the CPU support list. Note some cheaper boards may only support CPU's up to 95W which is why it's important to check first.

For modern games you need a quad core chip, there are quite a few that should work even if it is a 95W mobo. As Eagle said you need a better power supply (I'm assuming the one you have will be a generic 400W supply). I'd strongly recommend getting a branded PSU like Coolermaster, as the OEM models are usually pretty bad. Ideally for supporting a good graphics card you want something with at least 32A on the 12V rail (note NOT 2 x 16A rails). As for the graphics card- if you want to keep costs down the 7850 1 Gb model is really good value, as is the newly released 7790 (should be available in a couple of weeks). Both of these cards are enough to game at 1080p with decent settings and 50fps average in almost any game. The 7870 cards and above are best suited for very high resolution screens / multi monitors or very high levels of AA. The other thing you need to check is that the mother board has a PCIE x16 slot for the graphics card (most boards do, however if its a branded system e.g. from Dell or HP, I have come across boards in the past without a graphics card slot- usually for small form factor machines).

If you need some more help, list the make and model of your motherboard, and a budget for parts and I could give you some more specific options.

this is what i am wanting....
CPU: Intel® Core™ i5-3570K 3.40 GHz 6MB Intel Smart Cache LGA1155 (All Venom OC Certified) [-114]
HDD: 500GB Western Digital Caviar Blue SATA-III 6.0Gb/s 7200 RPM HDD [-12] (Single Drive)
MEMORY: 8GB (4GBx2) DDR3/1600MHz Dual Channel Memory (Corsair or Major Brand)
MOTHERBOARD: * [CrossFireX] ASUS P8Z77-V LX Intel Z77 Chipset DDR3 ATX Mainboard w/ IRST, Lucid Virtu MVP, 7.1 HD Audio, GbLAN, 2x PCIe x16 (1 Gen3, 1 Gen2), 2x PCIe x1 & 3 PCI (Extreme OC Certified)
SOUND: HIGH DEFINITION ON-BOARD 7.1 AUDIO
VIDEO: NVIDIA GeForce GTX 650 Ti 2GB 16X PCIe Video Card [+29] (Major Brand Powered by NVIDIA)

this should be able to run it at 50 fps??
 


That would depend on what resolution you'd be running at? That is a very nice system although the 650 Ti is a little slow (that card has a rather limited memory bandwidth). I'd personally try and up the graphics card to a Radeon 7850 if you can stretch to it...
