1 card people should seriously look at:
Asus ti4200 v8420
Here is an excerpt from the review on hardocp:
"Because of the "budget" nature of the Ti4200 as a whole, trade offs are made when it comes to the memory and configuration. Normally you can either have 64MB of faster memory, or 128MB of slower memory, making it somewhat of a difficult decision when choosing between the two. Most 128MB Ti4200 cards use the 4.0ns memory, while the 64MB variety tends to use the faster 3.6ns. The V8420 has eliminated this dilemma by offering 128MB of the 3.3ns BGA memory; you can have your cake and eat it too."
If I were in the market for a ti4200, I'd be grabbing this this in a heartbeat. Here is the memory calculation from hardocp as well...looks like it has the overclocking ability never seen in a ti4200 card:
(3.3ns memory) 1000 / 3.3 = 606 MHz
Looks like this thing should clock to a little over 600 MHz.. but here is what HArdocp managed:
Stock speeds on the ASUS V8420 GeForce4 Ti 4200 start out at 260MHz core and 550MHz (DDR) memory. By enabling the coolbits hack I moved the Ti4200 up to a respectable 310MHz core clock. Considering the card is factory overclocked already, it performed very well. Memory scores topped out at 640, which is head and shoulders above the other Ti4200's, putting within reaching distance of stock Ti4600 memory speeds. Taking into consideration the core speed is already overclocked at 260MHz, getting the extra 50MHz on the core was pretty impressive. The 3.3ns Samsung BGA memory rated at 600MHz performed flawlessly at 640. I had hoped for more, but 650 brought on the tearing and artifacting until it was backed down to 640.
OMG...10 MHz under the stock speed of the ti4600? I think that looks impressive indeed.
